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.

rtc: sun6i: disable automatic clock input switching

2024-09-11T22:33:33Z

The V3(s) will detect a valid external low frequency clock and if it is not present will automatically switch to the internal one. This might hide bugs and (hardware) configuration errors. It's even worse because the internal RTC runs significantly slower (32.000Hz vs 32.768Hz). Fortunately for us, the V3(s) has an (undocumented) bypass of this switching and the driver already supports it by setting the .has_auto_swt flag.

rtc: s35390a: Drop vendorless compatible string from match table

2024-09-11T22:15:49Z

There's no need to list "s35390a" in the DT match table. The I2C core will strip any vendor prefix and match against the i2c_device_id table which has an "s35390a" entry.
