wm8350_power: 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> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
