lirc: rc_dev_get_from_fd(): fix file leak

2024-08-03T07:01:04Z

[ Upstream commit bba1f6758a9ec90c1adac5dcf78f8a15f1bad65b ] missing fdput() on a failure exit Fixes: 6a9d552483d50 "media: rc: bpf attach/detach requires write permission" # v6.9 Signed-off-by: Al Viro Signed-off-by: Sasha Levin

media: lirc_dev: Make lirc_class constant

2024-03-25T09:13:44Z

Since commit 43a7206b0963 ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the lirc_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.

media: lirc: drop trailing space from scancode transmit

2023-10-11T14:26:16Z

When transmitting, infrared drivers expect an odd number of samples; iow without a trailing space. No problems have been observed so far, so this is just belt and braces.

driver core: class: remove module * from class_create()

2023-03-17T14:16:33Z

The module pointer in class_create() never actually did anything, and it shouldn't have been requred to be set as a parameter even if it did something. So just remove it and fix up all callers of the function in the kernel tree at the same time. Cc: "Rafael J.

media: rc: Directly use ida_free()

2022-06-20T09:30:33Z

Use ida_alloc() and ida_free() instead of the deprecated ida_simple_get() and ida_simple_remove(). Signed-off-by: keliu Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: report ir receiver overflow

2022-01-28T18:32:50Z

If the driver reports that the hardware had an overflow, report this to userspace. It would be nice to know when this happens, and not just get a long space. This change has been tested with lircd, ir-ctl, and ir-keytable. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc-core: rename ir_raw_event_reset to ir_raw_event_overflow

2022-01-28T18:32:50Z

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: lirc: simplify gap calculation

2022-01-24T00:38:32Z

When a driver reports a timeout, no more IR activity will be reported until the next pulse. A space is inserted between the timeout and the next pulse, based on ktime. The timeout reports already a duration, so this duration should not be added to the gap. Otherwise there is no change to the functionality.

media: lirc: always send timeout reports

2021-12-14T14:09:12Z

Without timeout reports, it is impossible to decode many protocols since it is not known when the transmission ends. timeout reports are sent by default, but can be turned off. There is no reason to turn them off, and I cannot find any software which does this, so we can safely remove it. This makes the ioctl LIRC_SET_REC_TIMEOUT_REPORTS a no-op.
