In case __get_free_pages fails, the fix releases resources and
return -ENOMEM to avoid NULL pointer dereferences.
Also, the fix frees pages when video_register_device fails to
avoid a memory leak.

Lockdep warns that prepare_lock and genpd->mlock can cause a deadlock
the deadlock scenario is like following:
First thread is probing cs2000
cs2000_probe()
clk_register()
__clk_core_init()
clk_prepare_lock()> acquires prepare_lock
Regarding: """While we are here I'd suggest if we can also fix the few
errors (3)
and warnings (5) spotted by checkpatch. With that it's an ack from my
side."""
These errors and warning are for code that is not used by the kernel:
WARNING: __aligned(size) is preferred over

Hi Angus,
My impression was that for arm64 world there will be only one
defconfig. So, I'm not
sure if this patch would be acceptable.
thanks,

Hmm, this seems a bit different what I suggested.
I'm trying to port probe event's error report on
your error

create_singlethread_workqueue may fail and return NULL. The fix
checks if it is NULL to avoid NULL pointer dereference.
Also, the fix moves the call of create_singlethread_workqueue
earlier to avoid resource-release issues.
