MIPS: TXx9: 7segled: use permission-specific DEVICE_ATTR variants
Use DEVICE_ATTR_WO for write 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>
@wo@
declarer name DEVICE_ATTR;
identifier x,x_store;
@@
DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store);
@script:ocaml@
x << wo.x;
x_store << wo.x_store;
@@
if not (x^"_store" = x_store) then Coccilib.include_match false
@@
declarer name DEVICE_ATTR_WO;
identifier wo.x,wo.x_store;
@@
- DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store);
+ DEVICE_ATTR_WO(x);
// </smpl>
