[PATCH v2 0/6] PWM JZ4740 fixes and cleanups

[Paul Cercueil]

Hi Thierry,

I rebased my patchset on top of v5.2-rc3 since it didn't apply anymore.
Patches 1-4 are unmodified. The old patch 5 added a SPDX license
notifier, but somebody else added it in -rc3 apparently, so I dropped
it. In the meantime I added two more cleanups.

Cheers
-Paul
