From: Roy Franz Date: Fri, 4 Oct 2013 16:02:46 +0000 (-0700) Subject: boot, efi: Remove redundant memset() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c158c3bf59951bbb44bd7ccca9e6665dfd1617c5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git boot, efi: Remove redundant memset() Remove a redundant memset() call from efi_relocate_kernel() that was clearing memory that would be used by BSS in non-compressed images loaded with this function. This clear was redundant with the clearing done in the image itself, and also implemented incorrectly with a 0 length.
