Subject: [PATCH] lib/string.c cleanup: restore useful memmove const
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=82da2c372712c772134d01317aa2517c923a74f8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[PATCH] lib/string.c cleanup: restore useful memmove const

A couple of (char *) casts removed in a previous cleanup patch in
lib/string.c:memmove() were actually useful, as they suppressed a couple of
warnings:

	assignment discards qualifiers from pointer target type

Fix by declaring the local variable const in the first place, so casts
aren't needed to strip the const qualifier.
