Subject: kconfig: use memcmp instead of deprecated bcmp
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0a1eab129fedb4281e65c845b04be02b53c99f9c;p=thirdparty%2Fkernel%2Flinux.git

kconfig: use memcmp instead of deprecated bcmp

bcmp() was removed in POSIX.1-2008.

This commit replaces bcmp() with memcmp(). This allows Kconfig to link
with C libraries that do not provide bcmp(), such as Android bionic
libc.
