Re: [PATCH] gpio: ml-ioh: use raw_spinlock_t for the register lock

[Junjie Cao]

Hi Linus,

Thanks for the review.

I checked it, and the report is correct. The PM callbacks take
chip[0].spinlock while the save and restore helpers walk all eight
channels, each with its own lock.

I have a follow-up that uses one lock shared by all channels. I'll send
it separately on top of this patch.

Thanks,
Junjie
