Subject: [PATCH] mt76: mt7921: Fix the error handling path of mt7921_pci_probe()
Git-commit: 4e90db5e21eb3bb272fe47386dc3506755e209e9
Patch-mainline: v5.19-rc1
References: git-fixes
In case of error, some resources must be freed, as already done above and
below the devm_kmemdup() and __mt7921e_mcu_drv_pmctrl() calls added in the
commit in Fixes:.
