[ Upstream commit ec8b6f55b98146c41dcf15e8189eb43291e35e89 ]
If we remove a GPIO chip that is also an interrupt controller with users not having freed some interrupts, we'll end up leaking resources as indicated by the following warning:
remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'gpio'
As there's no way of notifying interrupt users about the irqchip going away and the interrupt subsystem is not plugged into the driver model and so not all cases can be handled by devlinks, we need to make sure to free all interrupts before the complete the removal of the provider.

The target value of scldiv is just a byte, but its calculation in fsl_lpspi_set_bitrate could be negative. So use an adequate type to store the result and avoid overflows. After that this needs range check adjustments, but this should make the code less opaque.

We already have the possibility to force not binding to hid-generic and rely on a dedicated driver, but we couldn't do the other way around.
This is useful for BPF programs where we are fixing the report descriptor and the events, but want to avoid a specialized driver to come after BPF which would unwind everything that is done there.

The QCM6490 is a variant of SC7280, with the usual set of protection domains, and hence the need for a PD-mapper. In particular USB Type-C port management and battery management is pmic_glink based.
Add an entry to the kernel, to avoid the need for userspace to provide this service.

If the wait_prepare or wait_finish callback is set, then call it. If it is NULL and the queue lock pointer is not NULL, then just unlock/lock that mutex.
This allows simplifying drivers by dropping the wait_prepare and wait_finish ops (and eventually the vb2_ops_wait_prepare/finish helpers).

Add Dexatek Technology Ltd USB Video Grabber 1d19:6108 to the cx231xx driver. This device is sold under the name "BAUHN DVD Maker (DK8723)" by ALDI in Australia.
This device is similar to 1d19:6109, which is already included in cx231xx.
Both video and audio capture function correctly after installing the patched cx231xx driver.
Patch Changelog v1: - Initial submission. v2: - Fix SoB + Improve subject. v3: - Rephrase message to not exceed 75 characters per line. - Removed reference to external GitHub URL.

GIGASTONE Gaming Plus microSD cards manufactured on 02/2022 report that they support poweroff notification and cache, but they are not working correctly.
Flush Cache bit never gets cleared in sd_flush_cache() and Poweroff Notification Ready bit also never gets set to 1 within 1 second from the end of busy of CMD49 in sd_poweroff_notify().
This leads to I/O error and runtime PM error state.
I observed that the same card manufactured on 01/2024 works as expected.
This problem seems similar to the Kingston cards fixed with commit c467c8f08185 ("mmc: Add MMC_QUIRK_BROKEN_SD_CACHE for Kingston Canvas Go Plus from 11/2019") and should be handled using quirks.
CID for the problematic card is here. 12345641535443002000000145016200
Manufacturer ID is 0x12 and defined as CID_MANFID_GIGASTONE as of now, but would like comments on what naming is appropriate because MID list is not public and not sure it's right.

Enable SDHCI_QUIRK_NO_LED for i.MX7ULP, i.MX8MM, i.MX8QXP and i.MXRT1050. Even there is LCTL register bit, there is no IOMUX PAD for it. So there is no sense to enable LED for SDHCI for these SoCs.

With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. This was not detected during regular testing without driver_async_probe.
Convert the SoC code to platform driver and instantiate a platform device in its current device_initcall() to probe the platform driver. Rework .soc_revision callback to always return valid error code and return SoC revision via parameter. This way, if anything in the .soc_revision callback return -EPROBE_DEFER, it gets propagated to .probe and the .probe will get retried later.

[ Upstream commit 9bc089307e8dff7797233308372b4a90ce8f79be ]
Mistel MD770 keyboard (using Holtek Semiconductor, Inc. controller) has a quirk in report descriptor in one of its interfaces (more detail in the source file). Fix up the descriptor to allow NKRO to work again.
Tested by loading the BPF program and confirming that 8 simultaneous keypresses work.

In the example above, the validator seems to get the scope of dependencies wrong, since the regmap instance used in rk8xx-spi driver has nothing to do with the instance from vop2.
Improve validation by sharing the regmap's lockdep class with the maple tree's internal lock, while also providing a subclass for the latter.

[ Upstream commit 46058430fc5d39c114f7e1b9c6ff14c9f41bd531 ]
resctrl selftests discover system properties via a variety of sysfs files. The MBM and MBA tests need to discover the event and umask with which to configure the performance event used to measure read memory bandwidth. This is done by parsing the contents of /sys/bus/event_source/devices/uncore_imc_<imc instance>/events/cas_count_read Similarly, the resctrl selftests discover the cache size via /sys/bus/cpu/devices/cpu<id>/cache/index<index>/size.
Take care to do bounds checking when using fscanf() to read the contents of files into a string buffer because by default fscanf() assumes arbitrarily long strings. If the file contains more bytes than the array can accommodate then an overflow will occur.
Provide a maximum field width to the conversion specifier to protect against array overflow. The maximum is one less than the array size because string input stores a terminating null byte that is not covered by the maximum field width.

Adds driver support for the USB-C model of Apple's Magic Trackpad 2.
The 2024 USB-C model is compatible with the existing Magic Trackpad 2 driver but has a different hardware ID.
