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

+ DEVICE_ATTR_RW(x);
