Subject: [PATCH] video: fbdev: intelfb: remove impossible condition
Date: Wed, 31 Aug 2016 15:56:29 +0000 [thread overview]
Message-ID: <1472658269-1234-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)
xoffset and yoffset of struct fb_var_screeninfo are unsigned and so
they can never be less than 0.
