During resume() GFP_NOIO is enough. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: remove third argument of usb_maxpacket()

2022-04-23T08:33:53Z

The third argument of usb_maxpacket(): in_out has been deprecated because it could be derived from the second argument (e.g. using usb_pipeout(pipe)). N.B. function usb_maxpacket() was made variadic to accommodate the transition from the old prototype with three arguments to the new one with only two arguments (so that no renaming is needed). The variadic argument is to be removed once all users of usb_maxpacket() get migrated.

media: streamzap: remove redundant gap calculations

2021-12-14T14:09:13Z

The lirc core already introduces gaps, so there is no need for this in the driver. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: streamzap: remove unused struct members

2021-12-14T14:09:13Z

These struct members do not serve any purpose. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: streamzap: less chatter

2021-12-14T14:09:13Z

Remove superfluous messages which add no information. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: streamzap: no need for usb pid/vid in device name

2021-12-14T14:09:13Z

The usb pid/vid can be found elsewhere, the idVendor/idProduct usb sysfs files for example. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: streamzap: remove unnecessary ir_raw_event_reset and handle

2021-12-14T14:09:13Z

There is no reason to have a reset after an IR timeout. Calling ir_raw_event_handle() twice for the same interrupt has no affect. Fixes: 56b0ec30c4bc ("[media] rc/streamzap: fix reporting response times") Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: streamzap: ensure rx resolution can be retrieved

2021-09-30T08:07:40Z

The receiver resolution is not populated. The resolution can be used to for various purposes like calculating the margins the decoder should use. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: harmonize infrared durations to microseconds

2020-09-03T14:18:55Z

rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done. This affects: - rx_resolution member of struct rc_dev - timeout member of struct rc_dev - duration member in struct ir_raw_event Cc: "Bruno Prémont" Cc: Hans Verkuil Cc: Maxim Levitsky Cc: Patrick Lerda Cc: Kevin Hilman Cc: Neil Armstrong Cc: Jerome Brunet Cc: Martin Blumenstingl Cc: Sean Wang Cc: Matthias Brugger Cc: Patrice Chotard Cc: Maxime Ripard Cc: Chen-Yu Tsai Cc: "David Härdeman" Cc: Benjamin Valentin Cc: Antti Palosaari Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
