Subject: [PATCH 0/4] pwm: Ensure .polarity is set in .get_state()

Hello,

in the context of the discussion with Munehisa Kamata about the meson driver
not setting .polarity in .get_state() I checked the other drivers for the same
issue. The identified drivers are fixed here. For three of them
zero-initializing *state would be good enough, still I think setting the
polarity explicitly is a good idea. For the hibvt driver (that supports
both polarities) the change is a real improvement.

Note I didn't touch the meson driver here that requires some non-trivial
updates that I don't want to tackle without hardware to test.

Best regards
Uwe
