From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Gustavo A. R. Silva" Date: Sat, 08 Jul 2017 01:24:16 +0000 Subject: [PATCH] video: xilinxfb: constify fb_fix_screeninfo and fb_var_screeninfo structures Message-Id: <20170708012416.GA1843@embeddedgus> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-arm-kernel@lists.infradead.org These structures are only used to copy into other structures, so declare them as const. This issue was detected using Coccinelle and the following semantic patch: @r disable optional_qualifier@ identifier i; position p; @@ static struct fb_fix_screeninfo i@p = { ... }; @ok@ identifier r.i; expression e; position p; @@ e = i@p @bad@ position p != {r.p,ok.p}; identifier r.i; struct fb_fix_screeninfo e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct fb_fix_screeninfo i = { ... }; The semantic patch for fb_var_screeninfo is analogous.
