2019-01-28Input: pwm-vibra - stop regulator after disabling pwm, not beforePaweł Chmiel
This patch fixes order of disable calls in pwm_vibrator_stop. Currently when starting device, we first enable vcc regulator and then setup and enable pwm. When stopping, we should do this in oposite order, so first disable pwm and then disable regulator. Previously order was the same as in start.

2019-01-28Input: pwm-vibra - prevent unbalanced regulatorJonathan Bakker
pwm_vibrator_stop disables the regulator, but it can be called from multiple places, even when the regulator is already disabled. Fix this by using regulator_is_enabled check when starting and stopping device.
