[PATCH v8 06/14] alpha: Align prototypes of IO memcpy/memset
From: Julian Vetter <hidden>
Date: 2024-10-08 07:55:04
Also in:
linux-alpha, linux-arch, linux-arm-msm, linux-m68k, linux-s390, linux-sh, linux-sound, linux-um, lkml, loongarch
Subsystem:
alpha port, the rest · Maintainers:
Richard Henderson, Matt Turner, Magnus Lindholm, Linus Torvalds
Align the prototypes of the memcpy_{from,to}io and memset_io functions
with the new ones from iomap_copy.c and remove function declarations,
because they are now declared in asm-generic/io.h.

Changes for v8:
- Mask the argument with 0xff because now it's an int and not a u8
anymore
