Subject: [PATCH] video: cobalt_lcdfb: constify fb_fix_screeninfo structure
Date: Fri, 7 Jul 2017 20:30:23 -0500	[thread overview]
Message-ID: <20170708013023.GA4842@embeddedgus> (raw)

This structure is only used to copy into other structures,
so declare it as const.

This issue was detected using Coccinelle and the following semantic patch:

static struct fb_fix_screeninfo i@p = { ... };

@ok@
