[PATCH] witherspoon: leds: Use underscore in led names than hyphen

[Vishwanatha Subbanna]

udev rule for leds subsystem in Witherspoon launches a systemd
service file with $devpath. If the devpath is
sys-devices-platform-leds-leds-rear-fault, systemd service file
interprets it as /sys/devices/platform/leds/leds/rear/fault.

However, what is really needed by the service file is
/sys/devices/platform/leds/leds/rear-fault.

This is a limitation in current systemd with template argument
containing hyphen. Short term solution is to have $name contain
underscores.

It would then become: /sys/devices/platform/leds/leds/rear_fault
and hence will work.

Refer systemd bug: https://github.com/systemd/systemd/issues/5072
