move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23+00:00

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Input: tablet - use sizeof(*pointer) instead of sizeof(type)

2024-06-03T04:32:03+00:00

It is preferred to use sizeof(*pointer) instead of sizeof(type) due to the type of the variable can change and one needs not change the former (unlike the latter). This patch has no effect on runtime behavior.

Input: aiptek - switch to using dev_groups for driver-specific attributes

2022-09-03T19:31:18+00:00

The driver core now has the ability to handle the creation and removal of device-specific sysfs files, let's use it instead of registering and unregistering attributes by hand.

Input: aiptek - remove redundant assignment to variable ret

2022-04-20T20:41:17+00:00

Variable ret is being assigned a value that is never read, it is being re-assigned again in either path of the if statement. The assignment is redundant and can be removed.

Input: aiptek - properly check endpoint type

2022-03-15T01:15:11+00:00

Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. There was a check for the number of endpoints, but not for the type of endpoint.

Input: aiptek - use descriptors of current altsetting

Make sure to always use the descriptors of the current alternate setting to avoid future issues when accessing fields that may differ between settings.

Input: aiptek - fix endpoint sanity check

2020-01-10T22:42:54+00:00

The driver was checking the number of endpoints of the first alternate setting instead of the current one, something which could lead to the driver binding to an invalid interface. This in turn could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.
