[PATCH 46/66] hwmon: (pc87427) use permission-specific DEVICE_ATTR variants

[Julia Lawall]

Use DEVICE_ATTR_RO etc. for read only attributes etc.  This simplifies the
source code, improves readbility, and reduces the chance of
inconsistencies.

The semantic patch for the RO case, in the case where the show function
already has the expected name, 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>
