tty: nozomi: use permission-specific DEVICE_ATTR variants
Use DEVICE_ATTR_RO for read only 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>
@ro@
declarer name DEVICE_ATTR;
identifier x,x_show;
@@
DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL);
@script:ocaml@
x << ro.x;
x_show << ro.x_show;
@@
if not (x^"_show" = x_show) then Coccilib.include_match false
@@
declarer name DEVICE_ATTR_RO;
identifier ro.x,ro.x_show;
@@
- DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL);
+ DEVICE_ATTR_RO(x);
// </smpl>
