From 4895398d0375d57fc098c2816eb0a7dadc1c1ce6 Mon Sep 17 00:00:00 2001 From: Prasant Jalan Date: Sat, 1 Apr 2017 00:40:01 +0530 Subject: staging: sm750fb: fixing function return with lock held lynxfb_suspend() & lynxfb_resume() return on errors while holding console_lock. Adding 'goto' such that proper cleanups can be done before returning from function and therefore console_lock can be released before returning.
