media: rc: igorplugusb: heed coherency rules

2026-05-07T04:13:50+00:00

commit eac69475b01fe1e861dfe3960b57fa95671c132e upstream. In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately.

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37+00:00

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

media: igorplugusb: use correct size pass to igorplugusb_probe()

2022-07-15T13:52:20+00:00

After 'buf_in' change to pointer, the sizeof() is not correct buffer size, it should be MAX_PACKET. Fixes: b3f820b905c9 ("media: igorplugusb: respect DMA coherency") Reported-by: Hulk Robot Signed-off-by: Yang Yingliang Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: igorplugusb: remove superfluous usb_unlink_urb()

2022-06-20T09:30:33+00:00

Calling that on yourself while the completion handler is running is a NOP. Remove it. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: igorplugusb: break cyclical race on disconnect

2022-06-20T09:30:33+00:00

The driver uses a timer, that may submit the URB and the URB may start the timer. No simple order of killing can break te cycle. Poison the URB before killing the timer. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: igorplugusb: prevent use after free in probe error

2022-06-20T09:30:33+00:00

The timer uses the URB. Free it only after the timer has been stopped. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: igorplugusb: respect DMA coherency

2022-06-20T09:30:32+00:00

The coherency rules mean that you cannot embed a buffer inside a descriptor. kmalloc() separately. Signed-off-by: Oliver Neukum Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc-core: rename ir_raw_event_reset to ir_raw_event_overflow

2022-01-28T18:32:50+00:00

The driver report a reset event when the hardware reports and overflow. There is no reason to have a generic "reset" event. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: igorplugusb: receiver overflow should be reported

2021-12-14T14:09:13+00:00

Without this, some IR will be missing mid-stream and we might decode something which never really occurred. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
