regulator: fix sysfs name collision between dummy and fixed dummy regulator
Shawn Guo [Sat, 31 Mar 2012 08:33:31 +0000 (16:33 +0800)]
When regulator_register_fixed() is being used to register fixed dummy
regulator, the following line will be seen in the boot log.  And the
sysfs entry for fixed dummy regulator is not shown.

  dummy: Failed to create debugfs directory

The patch renames the fixed dummy supply to "fixed-dummy" to avoid
the name collision with dummy regulator.
