Subject: [PATCH] Clean up arch-overrides in linux/string.h
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8833d328caf009f8da58337e17a2cf5d52993a7c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[PATCH] Clean up arch-overrides in linux/string.h

Some string functions were safely overrideable in lib/string.c, but their
corresponding declarations in linux/string.h were not.  Correct this, and
make strcspn overrideable.

Odds of someone wanting to do optimized assembly of these are small, but
for the sake of cleanliness, might as well bring them into line with the
rest of the file.
