Hello Kishon,

Could you take this patch through your tree?
It fixes a pair of nasty bugs.

I do have a follow-up (trivial) patch on top of this one:
https://lore.kernel.org/patchwork/patch/1088044/

What are your thoughts on the usleep_range issue?
https://lore.kernel.org/patchwork/patch/1088035/

Regards.
