Subject: [PATCH] staging: sm750fb: remove redundant pointer 'output'

From: Colin Ian King <colin.king@...onical.com>

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

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