| |
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>
