4cf95663c8 Regulators: virtual - use sysfs attribute groups 
Instead of open-coding sysfs attribute group use canned solution.
Also add __devinit/__devexit markups for probe and remove methods
and use 'bool' where it makes sense.

38c53c8913 regulator: Set MODULE_ALIAS for regulator drivers 
Several of the regulator drivers didn't have MODULE_ALIAS so couldn't be
auto loaded. Add the MODULE_ALIAS in case they do get built as modules.

oh, it's for the string sharing.  Sneaky.

I wonder how many people will try to fix that up for us?

93e14baa44 regulator: minor cleanup of virtual consumer 
Minor cleanup to the regulator set_mode sysfs support:
switch to sysfs_streq() in set_mode(), which is also
a code shrink.  Use the same strings that get_mode()
uses, shrinking data too.
