Just FYI, that patch prevents the kernel from booting due to a bug in
pm34xx.c; patch below.

Even with the follwoing patch, the initial power state setup code in
pm34xx.c will bail out early since it still tries to set the SGX next
power state to retention, which it does not support.

OMAP3 PM: use list_for_each_entry_safe() when deleting list entries

From: Paul Walmsley <paul@pwsan.com>

The error path in clkdms_setup() needs to use list_for_each_entry_safe()
when deleting entries from the list, or the kernel will crash.
