Subject: crypto: x86/sha1 - Rename conflicting symbol
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=56119446f89fbab40f3a160e9c3de33687cd85cf;p=thirdparty%2Flinux.git

crypto: x86/sha1 - Rename conflicting symbol

Rename x86's sha1_update() to sha1_update_x86(), since it conflicts with
the upcoming sha1_update() library function.

Note: the affected code will be superseded by later commits that migrate
the arch-optimized SHA-1 code into the library.  This commit simply
keeps the kernel building for the initial introduction of the library.
