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.

First off, sorry for the breakage. Second, while the patch is correct in
the part is covered, it is incomplete (it also should cover the
!CONFIG_PM_RUNTIME case. So, I think the appended patch would be better.
Thanks,

OK, below is an "official" version. Can you please double check if it fixes
the problem for you?

From: Rafael J. Wysocki <[email protected]>
Subject: PM / Runtime: Fix loops in pm_runtime_clk_notify()
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 those loops behave as appropriate.
This fixes a regression introduced by commit 600b776eb39a13a28b090
(OMAP1 / PM: Use generic clock manipulation routines for runtime PM).

Hi,
I've tested it successfully, but only the CONFIG_PM_RUNTIME=y case, not
the other because of still another McBSP issue, I believe, described
elswhere.

OK, thanks!
If the other case turns out to cause more problems, they'll need separate
fixes anyway.
