From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> [ Upstream commit 3ad4a31620355358316fa08fcfab37b9d6c33347 ] Last change to device managed APIs cleaned up error path to simple phy_exit() call, which in some cases has been executed with NULL parameter. This per se is not a problem, but rather logical misconception: no need to free resource when it's for sure has not been allocated yet. Fix the driver accordingly.
