[PATCH] GTA02: gps power management bugfix

[Paul Fertser]

After suspending with GPS powered on power_on sysfs node reports 0 and GPS
is actually unpowered but "echo 1 > power_on" has no effect. This patch
fixes it.

Reported and analised by Timo Juhani Lindfors <timo.lindfors at iki.fi>,
ticket #2293.
