2018-03-23media: tvaudio: improve error handlingMauro Carvalho Chehab
The error handling logic at tvaudio is broken on several ways, as it doesn't really check right when an error occurs.

Shuts up the following warnings: drivers/media/i2c/tvaudio.c:222 chip_read() error: uninitialized symbol 'buffer'. drivers/media/i2c/tvaudio.c:223 chip_read() error: uninitialized symbol 'buffer'.

2018-03-22media: cec: improve CEC pin event handlingHans Verkuil
It turns out that the struct cec_fh event buffer size of 64 events (64 for CEC_EVENT_PIN_CEC_LOW and 64 for _HIGH) is too small. It's about 160 ms worth of events and if the Raspberry Pi is busy, then it might take too long for the application to be scheduled so that it can drain the pending events. Increase these buffers to 800 events which is at least 2 seconds worth of events. There is also a FIFO in between the interrupt and the cec-pin thread. The thread passes the events on to the CEC core. It is important that should this FIFO fill up the cec core will be informed that events have been lost so this can be communicated to the user by setting CEC_EVENT_FL_DROPPED_EVENTS. It is very hard to debug CEC problems if events were lost without informing the user of that fact. If events were dropped due to the FIFO filling up, then the debugfs status file will let you know how many events were dropped.

2018-03-22media: rcar-vin: use scratch buffer and always run in continuous modeNiklas Söderlund
Instead of switching capture mode depending on how many buffers are available use a scratch buffer and always run in continuous mode. By using a scratch buffer the responsiveness of the capture loop is increased as it can keep running even if there are no buffers available from userspace. As soon as a userspace queues a buffer it is inserted into the capture loop and returned as soon as it is filled. This is a improvement on the previous logic where the whole capture loop was stopped and switched to single capture mode if userspace did not feed the VIN driver buffers at the same time it consumed them. To make matters worse it was difficult for the driver to reenter continuous mode if it entered single mode even if userspace started to queue buffers faster. This resulted in suboptimal performance where if userspace where delayed for a short period the ongoing capture would be slowed down and run in single mode until the capturing process where restarted. An additional effect of this change is that the capture logic can be made much simple as we know that continuous mode will always be used.

Before starting a capture, allocate a scratch buffer which can be used by the driver to give to the hardware if no buffers are available from userspace. The buffer is not used in this patch but prepares for future refactoring where the scratch buffer can be used to avoid the need to fallback on single capture mode if userspace can't queue buffers as fast as the VIN driver consumes them.

2018-03-22media: ttpci: improve printing of encoded MAC addressDaniel Scheller
When loading the budget_av driver for ie. a KNC1 DVB-C TDA10024 card, which makes use of the ttpci eeprom check functionality (that always fails on these cards, but that's no issue at all), this is printed to the kernel log: [ 10.497333] saa7146 (0): dma buffer size 192512 [ 10.497335] dvbdev: DVB: registering new adapter (KNC1 DVB-C TDA10024) [ 10.545007] adapter failed MAC signature check [ 10.545009] encoded MAC from EEPROM was [ 10.545010] ff: [ 10.545011] ff: [ 10.545011] ff: ... [ 10.545021] ff [ 10.832422] budget_av: KNC1-4: MAC addr = 00:09:d6:6d:b3:be with the 'ff' being repeated for a total of 20 times. Improve that by using the %*phC format specifier instead dprintk()'ing every byte of the encoded MAC separately. This obsoletes the int i, and the kernel log looks cleaner: [ 3234.383153] saa7146 (0): dma buffer size 192512 [ 3234.383154] dvbdev: DVB: registering new adapter (KNC1 DVB-C TDA10024) [ 3234.428745] adapter failed MAC signature check [ 3234.428747] encoded MAC from EEPROM was ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff [ 3234.728194] budget_av: KNC1-0: MAC addr = 00:09:d6:6d:b3:be Signed-off-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

Unfortunately, my build process was also broken, as it was reporting me that the compilation went fine: $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/staging/media $ make ARCH=i386 CF=-D__CHECK_ENDIAN__ CONFIG_DEBUG_SECTION_MISMATCH=y C=1 W=1 CHECK='compile_checks' M=drivers/media *** ERRORS *** *** WARNINGS *** compilation succeeded That was due to a change here to use of linux-log-diff script that provides a diffstat between the errors output. Somehow, the logic was missing some fatal errors.
