video: fbdev: wm8505fb use permission-specific DEVICE_ATTR variants
Use DEVICE_ATTR_RW for read-write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @rw@ declarer name DEVICE_ATTR; identifier x,x_show,x_store; @@ DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); @script:ocaml@ x << rw.x; x_show << rw.x_show; x_store << rw.x_store; @@ if not (x^"_show" = x_show && x^"_store" = x_store) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_RW; identifier rw.x,rw.x_show,rw.x_store; @@ - DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); + DEVICE_ATTR_RW(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
