pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()

2024-06-12T09:12:24+00:00

[ Upstream commit c748a6d77c06a78651030e17da6beb278a1c9470 ] In order to introduce a pwm api which can be used from atomic context, we will need two functions for applying pwm changes: int pwm_apply_might_sleep(struct pwm *, struct pwm_state *); int pwm_apply_atomic(struct pwm *, struct pwm_state *); This commit just deals with renaming pwm_apply_state(), a following commit will introduce the pwm_apply_atomic() function.

commit c8a489f820179fb12251e262b50303c29de991ac upstream. 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.

media: imon: fix access to invalid resource for the second interface

2023-11-28T17:19:47+00:00

[ Upstream commit a1766a4fd83befa0b34d932d532e7ebb7fab1fa7 ] imon driver probes two USB interfaces, and at the probe of the second interface, the driver assumes blindly that the first interface got bound with the same imon driver. It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

media: Explicitly include correct DT includes

2023-07-19T10:57:51+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

The driver can match only via the DT table so the table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it might not be relevant here).
