Subject[PATCH] staging: gasket: remove redundant pointer bar_data
Date
From: Colin Ian King <colin.king@canonical.com>

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

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