stable inclusion from linux-4.19.198 commit 54913394d67e7aea1e1834640cae284f2658f8b7
--------------------------------
[ Upstream commit b601a18f12383001e7a8da238de7ca1559ebc450 ]
A consumer is expected to disable a PWM before calling pwm_put(). And if they didn't there is hopefully a good reason (or the consumer needs fixing). Also if disabling an enabled PWM was the right thing to do, this should better be done in the framework instead of in each low level driver.
So drop the hardware modification from the .remove() callback.
