2013-01-03Drivers: media: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-07-30[media] radio-si470x: Always use interrupt to wait for tune/seek completionHans de Goede
Since USB receives STATUS_RSSI updates through the interrupt endpoint, there is no need to poll with USB, so get rid of the polling.

2012-07-30[media] radio-si470x: Don't unnecesarily read registers on G_TUNERHans de Goede
Reading registers from the pcear USB dongles with the si470x causes a loud pop (and an alsa buffer overrun). Since most radio apps periodically call G_TUNER to update mono/stereo, signal and afc status this leads to the music . pop . music . pop . music -> not good. On the internet there is an howto for flashing the pcear with a newer firmware from the silabs reference boardto fix this, but: 1) This howto relies on a special version of the driver which allows firmware flashing 2) We should try to avoid the answer to a bug report being upgrade your firmware, if at all possible 3) Windows does not suffer from the pop sounds After a quick look at the driver I found at that the register reads are not necessary at all, as the device gives us the necessary status through usb interrupt packets, and the driver already uses these!

2012-05-14[media] radio-si470x-usb: remove autosuspend, implement suspend/resumeHans Verkuil
The radio-si470x-usb driver supported both autosuspend and it stopped the radio the moment the last user of the radio device closed it. However, that was very confusing since if you play the audio from the device (e.g. through arecord -D ... | aplay) then no sound would play unless you had the radio device open at the same time, even though there is no need to do anything with that node. On the other hand, the actual suspend/resume functions didn't do anything, which would fail if you *did* have the radio node open at that time. So: - remove autosuspend (bad idea in general for USB radio devices) - move the start/stop out of the open/release functions into the resume/suspend functions.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

In si470x_usb_driver_disconnect() radio->disconnect_lock is accessed after it is freed. This fixes the problem. Coverity CID: 2530 Signed-off-by: Darren Jenkins <darrenrjenkins@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-02-26V4L/DVB (13948): radio: Correct use after freeJulia Lawall
It is not clear how to share the unlock in the case where the structure containing the lock has to be freed. So the unlock is now duplicated, with one copy moved before the free. The unlock label furthermore is no longer useful and is thus deleted. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,e; identifier f; iterator I; statement S; @@ *kfree(x); ... when != &x when != x = e when != I(x,...) S *x->f // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
