From 57626ff1c9135211b92dfbea1923333c7b6dd12c Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Mon, 18 May 2020 10:45:12 +0200 Subject: [PATCH] tty: n_gsm: Remove unnecessary test in gsm_print_packet() If the length is zero then the print_hex_dump_bytes won't output anything, so testing the length before the call is unnecessary.
