PM / Runtime: Fix loops in pm_runtime_clk_notify()
Rafael J. Wysocki [Tue, 7 Jun 2011 21:34:58 +0000 (23:34 +0200)]
The loops over connection ID strings in pm_runtime_clk_notify()
should actually iterate over the strings and not over the elements
of the first of them, so make them behave as appropriate.

This fixes a regression introduced by commit 600b776eb39a13a28b090
(OMAP1 / PM: Use generic clock manipulation routines for runtime PM).
