[PATCH 1/9] PM / Domains: Fix pm_genpd_poweron()

From: Rafael J. Wysocki
Date: Sun Jul 31 2011 - 13:54:05 EST


From: Rafael J. Wysocki <rjw@xxxxxxx>

The local variable ret is defined twice in pm_genpd_poweron(), which
causes this function to always return 0, even if the PM domain's
.power_on() callback fails, in which case an error code should be
returned.

Remove the wrong second definition of ret and additionally remove an
unnecessary definition of wait from pm_genpd_poweron().
