Subject: efi_selftest: remove redundant function efi_st_memcmp()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=8101dd3dfaa9bf85a80b76fc2be1ae59bd051bc9;p=u-boot.git

efi_selftest: remove redundant function efi_st_memcmp()

Function memcmp() is available in efi_freestanding.c. So we do not remove a
further implementation.

Replace all usages of efi_st_memcmp() by memcmp().
