pinctrl: core: Remove extra kref_get which blocks hogs being freed
commitaafd56fc79
upstream. kref_init starts with the reference count at 1, which will be balanced by the pinctrl_put in pinctrl_unregister. The additional kref_get in pinctrl_claim_hogs will increase this count to 2 and cause the hogs to not get freed when pinctrl_unregister is called. Fixes:6118714275
