2018-01-23media: dw9714: Call pm_runtime_idle() at the end of probe()Sakari Ailus1-0/+1
Call pm_runtime_idle() at the end of the driver's probe() function to enable the device to reach low power state once probe() finishes.

2018-01-23media: rc: do not remove first bit if leader pulse is presentSean Young4-10/+12
The rc5 protocol does not have a leading pulse or space, but we encode the first bit using a single leading pulse. For other protocols, the leading pulse or space does not represent any bit. So, don't remove the first bit if a leading pulse is present.

2018-01-23media: rc: clean up leader pulse/space for manchester encodingSean Young5-44/+24
The IR rc6 encoder sends the header using manchester encoding using 0 bits, which causes the following: UBSAN: Undefined behaviour in drivers/media/rc/rc-ir-raw.c:247:6 shift exponent 4294967295 is too large for 64-bit type 'long long unsigned int' So, allow the leader code to send a pulse and space and remove the unused pulse_space_start field.

2018-01-23media: lirc: lirc mode ioctls deal with current modeSean Young2-18/+62
The ioctl change the current mode or return the current mode; they do not tell you which modes are possible (use the lirc features ioctl for that). Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2018-01-23media: lirc: lirc daemon fails to detect raw IR deviceSean Young2-15/+13
Since commit 9b6192589be7 ("media: lirc: implement scancode sending"), and commit de142c324106 ("media: lirc: implement reading scancode") the lirc features ioctl for raw IR devices advertises two modes for sending and receiving. The lirc daemon now fails to detect a raw IR device, both for transmit and receive. To fix this, do not advertise the scancode mode in the lirc features for raw IR devices (however do keep it for scancode devices). The mode can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

2018-01-23media: lirc: add module alias for lirc_devSean Young1-0/+2
Since commit a60d64b15c20 ("media: lirc: lirc interface should not be a raw decoder"), there is no lirc_dev module any more. On Ubuntu 16.10, the /etc/init.d/lirc startup script attempts to load the lirc_dev module. Since this module does not exist any more, this script fails. Add an alias so the correct module is loaded.

2018-01-23media: lirc: don't kfree the uninitialized pointer txbufColin Ian King1-2/+3
The current error exit path if ir_raw_encode_scancode fails is via the label out_kfree which kfree's an uninitialized pointer txbuf. Fix this by exiting via a new exit path that does not kfree txbuf. Also exit via this new exit path for a failed allocation of txbuf to avoid a redundant kfree on a NULL pointer (to save a bunch of CPU cycles).
