In this particular case the regulator seems to be mandatory as they error out if
regulator_get() fails. Also, the comment above regulator_enable() said
the enabling
was done to fix some bug. Hence I wasn't sure if we could just print a
warning message
and continue further upon failure. I will change it as per your
suggestion and re-spin the patches.
