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

2024-10-02T21:23:23Z

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

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43Z

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

USB: misc: yurex: fix race between read and write

The write code path touches the bbu member in a non atomic manner without taking the spinlock. Fix it. The bug is as old as the driver.

USB: misc: cypress_cy7c63: check for short transfer

As we process the second byte of a control transfer, transfers of less than 2 bytes must be discarded. This bug is as old as the driver.

USB: appledisplay: close race between probe and completion handler

2024-09-13T05:54:23Z

There is a small window during probing when IO is running but the backlight is not registered. Processing events during that time will crash. The completion handler needs to check for a backlight before scheduling work. The bug is as old as the driver.

usb: misc: onboard_usb_dev: add Microchip usb5744 SMBus programming support

2024-09-11T13:36:25Z

usb5744 supports SMBus Configuration and it may be configured via the SMBus slave interface during the hub start-up configuration stage. To program it driver uses i2c-bus phandle (added in commit '02be19e914b8 dt-bindings: usb: Add support for Microchip usb5744 hub controller') to get i2c client device and then based on usb5744 compatible check calls usb5744 i2c default initialization sequence. Apart from the USB command attach, prevent the hub from suspend. when the USB Attach with SMBus (0xAA56) command is issued to the hub, the hub is getting enumerated and then it puts in a suspend mode. This causes the hub to NAK any SMBus access made by the SMBus Master during this period and not able to see the hub's slave address while running the "i2c probe" command. Prevent the MCU from putting the HUB in suspend mode through register write. The BYPASS_UDC_SUSPEND bit (Bit 3) of the RuntimeFlags2 register at address 0x411D controls this aspect of the hub. The BYPASS_UDC_SUSPEND bit in register 0x411Dh must be set to ensure that the MCU is always enabled and ready to respond to SMBus runtime commands. This register needs to be written before the USB attach command is issued. The byte sequence is as follows: Slave addr: 0x2d 00 00 05 00 01 41 1D 08 Slave addr: 0x2d 99 37 00 Slave addr: 0x2d AA 56 00 Also since usb5744 i2c initialization routine uses i2c SMBus APIs invoke these APIs only when i2c driver is enabled in the kernel configuration.

usb: misc: onboard_dev: extend platform data to add power on delay field

2024-09-11T13:36:25Z

Introduce dedicated field 'power_on_delay_us' in onboard platform data and update its delay for USB5744 configuration. Hub itself requires some delay after reset to get to state where configuration data is going to be accepted. Without delay upcoming support for configuration via SMBUS is reporting a failure on the first SMBus write. i2c 2-002d: error -ENXIO: BYPASS_UDC_SUSPEND bit configuration failed Similar delay is likely also required for default configuration but because there is enough time (code execution) between reset and usage of the hub any issue is not visible but it doesn't mean delay shouldn't be reflected.
