From a41458d74c241f2c39ee23fef88df166c3c26a85 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 8 Feb 2019 19:24:47 +0100 Subject: [PATCH] video/fbdev: refactor video= cmdline parsing Make the video_setup() function slightly easier to read by removing the repeated checks for !global. Remove the misleading return value comment while at it. I'm slightly hesitant to change any of this, but here goes anyway, with hopes that the next person to have to look at this has it a wee bit easier.
