If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2212947627037f51009e9fb743eb0a00098e1663 Author: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Date: Tue Jul 27 15:51:30 2021 +0300 ata: sata_dwc_460ex: No need to call phy_exit() befre phy_init() [ 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.
