Subject: apm821xx: WNDR4700: fix fan-control
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cf6849a6bf8002abf761dd25f74dd0b086b65fa2;p=openwrt%2Fstaging%2Fnbd.git

apm821xx: WNDR4700: fix fan-control

This service was unfunctional due to not having its executable bit set.
Furthermore, sysupgrade complains about the file being present in images.

Also, the tc654 driver doesn't provide pwm1_enable sysfs file, instead its
now called pwm1_mode.

Please note that the fan was always spinning. It should now turn off, when
there's enough the thermal headroom.
