Conor Dooley 5b4052aa95 clk: microchip: fix potential UAF in auxdev release callback ... commit 7455b7007b upstream. Similar to commit 1c11289b34 ("peci: cpu: Fix use-after-free in adev_release()"), the auxiliary device is not torn down in the correct order. If auxiliary_device_add() fails, the release callback will be called twice, resulting in a UAF. Due to timing, the auxdev code in this driver "took inspiration" from the aforementioned commit, and thus its bugs too! Moving auxiliary_device_uninit() to the unregister callback instead avoids the issue.
