[PATCH 5.3 093/135] pwm: bcm-iproc: Prevent unloading the driver module while in use

[Greg Kroah-Hartman]

From: Uwe Kleine-KÃnig <u.kleine-koenig@xxxxxxxxxxxxxx>

[ Upstream commit 24906a41eecb73d51974ade0847c21e429beec60 ]

The owner member of struct pwm_ops must be set to THIS_MODULE to
increase the reference count of the module such that the module cannot
be removed while its code is in use.

Fixes: daa5abc41c80 ("pwm: Add support for Broadcom iProc PWM controller")
