Use DEVICE_ATTR_RO etc. for read only attributes etc. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The complete semantic patch 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); @wo@ declarer name DEVICE_ATTR; identifier x,x_store; @@ DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store); @rw@ declarer name DEVICE_ATTR; identifier x,x_show,x_store; @@ DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); @script:ocaml@ x << ro.x; x_show << ro.x_show; @@ if not (x^"_show" = x_show) then Coccilib.include_match false @script:ocaml@ x << wo.x; x_store << wo.x_store; @@ if not (x^"_store" = x_store) then Coccilib.include_match false @script:ocaml@ x << rw.x; x_show << rw.x_show; x_store << rw.x_store; @@ if not (x^"_show" = x_show && x^"_store" = x_store) 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); @@ declarer name DEVICE_ATTR_WO; identifier wo.x,wo.x_store; @@ - DEVICE_ATTR(x, \(0200\|S_IWUSR\), NULL, x_store); + DEVICE_ATTR_WO(x); @@ declarer name DEVICE_ATTR_RW; identifier rw.x,rw.x_show,rw.x_store; @@ - DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); + DEVICE_ATTR_RW(x); // </smpl> --- arch/mips/txx9/generic/7segled.c | 4 ++-- arch/powerpc/kernel/iommu.c | 3 +-- arch/tile/kernel/sysfs.c | 14 +++++++------- drivers/atm/solos-pci.c | 2 +- drivers/pci/pcie/aspm.c | 4 ++-- drivers/power/supply/wm8350_power.c | 2 +- drivers/ptp/ptp_sysfs.c | 2 +- drivers/thermal/int340x_thermal/int3400_thermal.c | 2 +- drivers/thermal/thermal_hwmon.c | 2 +- drivers/tty/nozomi.c | 4 ++-- drivers/usb/wusbcore/dev-sysfs.c | 6 +++--- drivers/usb/wusbcore/wusbhc.c | 13 +++++-------- drivers/video/fbdev/wm8505fb.c | 2 +- sound/soc/omap/mcbsp.c | 4 ++-- sound/soc/soc-dapm.c | 2 +- 15 files changed, 31 insertions(+), 35 deletions(-)
