[PATCH 3.0-rc1] PM / runtime: fix broken iteration over clock ids

From: Janusz Krzysztofik
Date: Sun Jun 05 2011 - 10:20:06 EST


In its current form, pm_runtime_clk_notify() iterates through sub-
strings of pm_clk_notifier_block.con_ids[0] rather than consecutive
pm_clk_notifier_block.con_ids[] elements. As a noticeable result, McBSP1
port no longer worked for me on updated arch/arm/mach-omap1/pm_bus.c
(commit 600b776eb39a13a28b090ba9efceb0c69d4508aa, "OMAP1 / PM: Use
generic clock manipulation routines for runtime PM"), not being able to
activate "fck" when required.

Tested on Amstrad Delta.
