Subject: MIPS: LLVMLinux: Silence variable self-assignment warnings.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c775aa12307efecb00ea78265210535dc41cdd49;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

MIPS: LLVMLinux: Silence variable self-assignment warnings.

Remove variable self-assignments.
This silences a bunch of -Wself-assign warnings reported by clang.
The changed code can be compiled without warnings by both gcc and clang.
