Subject: [PATCH] tty: n_gsm: remove redundant pointer gsm

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

Pointer gsm is assigned a value that is never read, hence it is
redundant and can be removed. Cleans up clang warning:

drivers/tty/n_gsm.c:2979:2: warning: Value stored to 'gsm' is never read
