Subject: [PATCH] lib/string.c cleanup: remove pointless explicit casts
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=850b9247926693454f71e819883f4dc06184e25f;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[PATCH] lib/string.c cleanup: remove pointless explicit casts

The first two hunks of the patch really belongs in patch 1, but I missed
them on the first pass and instead of redoing all 3 patches I stuck them in
this one.
