...trcpy and memcpy by definition return dst, that's mostly useless. If you want it to return anything, please make it something that might be used - for example, having stpcpy semantics (returning a pointer to dst's terminating \0) means a caller might avoid a strlen call. - Maybe do strtoupper while you're at it. Quick grepping didn't find any use for the copy-while-lowercasing, but copy-while-uppercasing can at least be used in drivers/acpi/acpica/nsrepair2.c, drivers/gpu/drm/nouveau/nvkm/engine/fifo/gk104.c, drivers/power/power_supply_sysfs.c along with a bunch of inpla...

This series introduces a new generic function strtolower(), which converts strings to lowercase in-place, overwriting the original string. This kind of functionality is needed in several places in the kernel. Right now, everybody seems to be implementing their own copy of this function. So, we replace several custom "strtolower" implementations with this new library function. Another
