2024-07-08spi: add ch341a usb2spi driverJohannes Thumshirn3-0/+248
Add a driver for the QiHeng Electronics ch341a USB-to-SPI adapter. This driver is loosely based on the ch341a module from the flashrom project.

2024-07-08thermal: core: Fix list sorting in __thermal_zone_device_update()Rafael J. Wysocki1-6/+4
The order in which lists are sorted in __thermal_zone_device_update() is reverse with respect to what it should be due to a mistake in thermal_trip_notify_cmp(). Fix it and observe that it is not necessary to sort the lists in different orders. They can both be sorted in ascending order if way_down_list is walked in reverse order which allows the code to be slightly more straightforward (and less prone to silly mistakes).

Use strnlen() instead of strlen() on the algorithm and coefficient name string arrays in V1 wmfw files. In V1 wmfw files the name is a NUL-terminated string in a fixed-size array. cs_dsp should protect against overrunning the array if the NUL terminator is missing.

2024-07-08hwmon: (amc6821) Make reading and writing fan speed limits consistentGuenter Roeck1-4/+9
The default value of the maximum fan speed limit register is 0, essentially translating to an unlimited fan speed. When reading the limit, a value of 0 is reported in this case. However, writing a value of 0 results in writing a value of 0xffff into the register, which is inconsistent. To solve the problem, permit writing a limit of 0 for the maximim fan speed, effectively translating to "no limit". Write 0 into the register if a limit value of 0 is written. Otherwise limit the range to <1..6000000> and write 1..0xffff into the register. This ensures that reading and writing from and to a limit register return the same value while at the same time not changing reported values when reading the speed or limits. While at it, restrict fan limit writes to non-negative numbers; writing a negative limit does not make sense and should be reported instead of being corrected.

2024-07-08hwmon: (amc6821) Stop accepting invalid pwm valuesGuenter Roeck1-6/+8
The pwm value range is well defined from 0..255. Don't accept any values outside this range. This changes the valid range of pwm1_auto_point2_pwm from 0..254 to 0..255, meaning it can now be equivalent to not only pwm1_auto_point1_pwm (which is always 0) but also to pwm1_auto_point3_pwm (which is always 255). While that may not be practical, there seems to be no technical reason for preventing a user from doing it.

2024-07-08drm/bridge: adv7511: Fix Intermittent EDID failuresAdam Ford3-14/+23
In the process of adding support for shared IRQ pins, a scenario was accidentally created where adv7511_irq_process returned prematurely causing the EDID to fail randomly. Since the interrupt handler is broken up into two main helper functions, update both of them to treat the helper functions as IRQ handlers. These IRQ routines process their respective tasks as before, but if they determine that actual work was done, mark the respective IRQ status accordingly, and delay the check until everything has been processed. This should guarantee the helper functions don't return prematurely while still returning proper values of either IRQ_HANDLED or IRQ_NONE.

In these cases, the SD card slot becomes non-functional as Linux continuously attempts to set the bus clock to 400 KHz. If the controller is incapable of getting that low, set its minimum frequency instead. While this may eliminate some SD cards, it allows those capable of operating at the controller's minimum frequency to be used.

Unique mount ids start past the last valid old mount id value to not confuse the two. If a last mount id has been specified, reject any invalid values early. Link: https://lore.kernel.org/r/20240704-work-mount-fixes-v1-2-d007c990de5f@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>

2024-07-07vfs: link_path_walk: move more of the name hashing into hash_name()Linus Torvalds1-19/+32
This avoids having to return the length of the component entirely by just doing all of the name processing in hash_name(). We can just return the end of the path component, and a flag for the DOT and DOTDOT cases. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-07-07vfs: link_path_walk: improve may_lookup() code generationLinus Torvalds1-10/+19
Instead of having separate calls to 'inode_permission()' depending on whether we're in RCU lookup or not, just share the first call. Note that the initial "conditional" on LOOKUP_RCU really turns into just a "convert the LOOKUP_RCU bit in the nameidata into the MAY_NOT_BLOCK bit in the argument", which is just a trivial bitwise and and shift operation. So the initial conditional goes away entirely, and then the likely case is that it will succeed independently of us being in RCU lookup or not, and the possible "we may need to fall out of RCU and redo it all" fixups that are needed afterwards all go in the unlikely path. [ This also marks 'nd' restrict, because that means that the compiler can know that there is no other alias, and can cache the LOOKUP_RCU value over the call to inode_permission(). ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2024-07-07hwmon: (w83627ehf) Fix underflows seen when writing limit attributesGuenter Roeck1-2/+2
DIV_ROUND_CLOSEST() after kstrtol() results in an underflow if a large negative number such as -9223372036854775808 is provided by the user. Fix it by reordering clamp_val() and DIV_ROUND_CLOSEST() operations. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
