2018-03-14staging: fsl-mc: Move DPBP out of stagingBogdan Purcareata
Move the source files out of staging into their final locations: - dpbp.c goes to drivers/bus/fsl-mc/, next to the core infrastructure - dpbp-cmd.h gets merged into drivers/bus/fsl-mc/fsl-mc-private.h, next to the other internally used APIs - dpbp.h gets merged into include/linux/fsl/mc.h, exposing the public API Update references in the dpaa2-eth staging driver. DPBP stands for Data Path Buffer Pool - you can read more about the object in Documentation/networking/dpaa2/overview.rst Signed-off-by: Bogdan Purcareata <bogdan.purcareata@nxp.com> Reviewed-by: Laurentiu Tudor <laurentiu.tudor@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-03-14staging: irda: remove the irda network stack and driversGreg Kroah-Hartman
No one has publicly stepped up to maintain this broken codebase for devices that no one uses anymore, so let's just drop the whole thing. If someone really wants/needs it, we can revert this and they can fix the code up to work properly. Cc: David S.

2018-03-14staging: vc04_services: Remove cache-line-size property (v3)Eric Anholt
It's been tempting to replace this with (L1) cache_line_size(), but that's really not what the value is about. It's about coordinating the condition for the pagelist fragment behavior between the two sides. However, the property was not accepted for the upstream DT binding, so we have to use the firmware's fallback value.

2018-03-14staging: lustre: fid: avoid false-positive uninitialized variable warningArnd Bergmann
One of Neil's recent cleanups apparently has led the code to get to a state where gcc tracks the 'seqnr' variable just enough to see that it is sometimes initialized in seq_client_alloc_seq(), but not enough that it can prove this initialization to be reliable before the use of that variable: drivers/staging/lustre/lustre/fid/fid_request.c: In function 'seq_client_alloc_fid': drivers/staging/lustre/lustre/fid/fid_request.c:245:22: error: 'seqnr' may be used uninitialized in this function [-Werror=maybe-uninitialized] The code seems to be otherwise correct, and I could not come up with a good way to simplify it further, so this adds a fake initialization to shut up that warning.

There are much better ways to do this these days. - Introduce some common functions to avoid various repititions. - Stop using mutex_trylock when mutex_lock and wait a bit is fine. - Improve error handling in various places. - Drop some 'Camel case' (which wasn't actually strickly camel case but was a bit odd. - Drop some _available sysfs attributes for things that don't exist (for particular supported parts).

2018-03-10staging: iio: tsl2x7x: make proximity sensor function correctlyBrian Masney
The bits for setting up the proximity diode were not setup correctly and this was causing the proximity sensor to not function correctly. This patch sets up the correct bit mask in tsl2x7x_chip_on() based on what the data sheet expects. From page 35 of the TSL2771 data sheet: https://ams.com/eng/content/download/250264/976045/file/TSL2771_DS000105_3-00.pdf - Bits 0-1 is the ALS gain control - Bits 2-3 is reserved (The proximity gain control on other tsl2x7x chips) - Bits 4-5 is the proximity diode select - Bits 6-7 is the LED drive strength tsl2x7x_chip_on() had the power and diode hardcoded, so these are extracted out into the settings so that these fields can be configured in the platform data. The default prox_gain is changed from 1 (2X gain) to 0 (1X gain) since the proximity gain control on the TSL2771, TMD2771, and other chips have these fields listed as reserved, and to write 0 into those bits. Verified that the proximity sensor now works correctly on a TSL2771 hooked up to a Raspberry Pi 2.
