2024-05-10backlight: otm3225a: Drop driver owner assignmentKrzysztof Kozlowski
Core in spi_register_driver() already sets the .owner, so driver does not need to.

2024-05-10backlight: lp8788: Drop support for platform dataUwe Kleine-König
The backlight driver supports getting passed platform data. However this isn't used. This allows to remove quite some dead code from the driver because bl->pdata is always NULL, and so bl->mode is always LP8788_BL_REGISTER_ONLY.

2024-05-10backlight: mp3309c: Fix signedness bug in mp3309c_parse_fwnode()Dan Carpenter
The "num_levels" variable is used to store error codes from device_property_count_u32() so it needs to be signed. This doesn't cause an issue at runtime because devm_kcalloc() won't allocate negative sizes. However, it's still worth fixing.

2024-05-10dt-bindings: mfd: aspeed: Drop 'oneOf' for pinctrl nodeRob Herring (Arm)
The use of 'oneOf' to include 1 of 3 possible child node schemas results in error messages containing the actual error message(s) for the correct SoC buried in the tons of error messages from the 2 schemas that don't apply. It also causes the pinctrl schema to be applied twice as it will be applied when the compatible matches. All that's really needed in the parent schema is to ensure one of the possible compatible strings is present in the pinctrl node so that its schema will be applied separately.

2024-05-10mfd: cs42l43: Update patching revision checkCharles Keepax
The firmware can only be patched once. The current code checks if the firmware supports the features required by the driver and then patches if it does not. This could lead to the device being patched twice if the device was patched before the driver took control, but with a firmware that doesn't support the features the driver requires. This would fail but potentially in unpredictable ways. The check should actually check the device is at the ROM version, and patch the device if it is. Then a separate later check should error out if the devices firmware is still too old to be supported. This will at least fail in a clean way with a nice error message.

2024-05-10perf sched: Rename 'switches' column header to 'count' and add usage ↵Madadi Vineeth Reddy
description, options for latency Rename 'Switches' to 'Count' and document metrics shown for perf sched latency output. Also add options possible with perf sched latency. Initially, after seeing the output of 'perf sched latency', the term 'Switches' seemed like it's the number of context switches-in for a particular task, but upon going through the code, it was observed that it's actually keeping track of number of times a delay was calculated so that it is used in calculation of the average delay. Actually, the switches here is a subset of number of context switches-in because there are some cases where the count is not incremented in switch-in handler 'add_sched_in_event'. For example when a task is switched-in while it's state is not ready to run(!= THREAD_WAIT_CPU). commit d9340c1db3f52460 ("perf sched: Display time in milliseconds, reorganize output") changed it from the original count to switches. So, renamed switches to count to make things a bit more clearer and added the metrics description of latency in the document.

2024-05-10perf tools: Ignore deleted cgroupsNamhyung Kim
On large systems, cgroups can be created and deleted often. That means there's a race between perf tools and cgroups when it gets the cgroup name and opens the cgroup. I got a report that 'perf stat' with many cgroups failed quite often due to the missing cgroups on such a large machine. I think we can ignore such cgroups when expanding events and use id 0 if it fails to read the cgroup id. IIUC 0 is not a vaild cgroup id so it won't update event counts for the failed cgroups.

2024-05-10perf parse-events: Add new 'fake_tp' parameter for testsDominique Martinet
The next commit will allow tracepoints starting with digits, but most systems do not have any available by default so tests should skip the actual "check if it exists in /sys/kernel/debug/tracing" step. In order to do that, add a new boolean flag specifying if we should actually "format" the probe or not.
