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> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> --- drivers/hwmon/i5k_amb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-hwmon" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
