Subject: bpf: sockmap: remove redundant pointer sg
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c23e014a4ba1a9448cbbd74916377f23a7da2fc2;p=linux.git

bpf: sockmap: remove redundant pointer sg

Pointer sg is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'sg' set but not used [-Wunused-but-set-variable]
