Description

The sysfs entry /sys/class/backlight/pcf50633-bl/bl_power is written inverse but reads out data "right".

Example:

root@om-gta02:~# cat /sys/bus/platform/devices/neo1973-pm-bt.0/power_on
0
root@om-gta02:~# echo 1 > /sys/bus/platform/devices/neo1973-pm-bt.0/power_on
root@om-gta02:~# cat /sys/bus/platform/devices/neo1973-pm-bt.0/power_on
0
root@om-gta02:~# echo 1 > /sys/bus/platform/devices/neo1973-pm-bt.0/power_on
root@om-gta02:~# cat /sys/bus/platform/devices/neo1973-pm-bt.0/power_on

  • Status changed from new to closed
  • HasPatchForReview unset
  • Resolution set to fixed

In the newer kernels

/sys/class/backlight/gta02-bl/bl_power

acts consistently inverted for read and write which is expected I believe.
