Subject: farsync: remove redundant variable txq_length
X-Git-Tag: v4.19~410^2~423
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=94c763513452b466d1e5c86b9d883ba13c9a031a;p=platform%2Fkernel%2Flinux-rpi.git

farsync: remove redundant variable txq_length

Variable txq_length is being assigned but is never used hence it is
redundant and can be removed.

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