6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miaoqian Lin linmq006@gmail.com
commit 1ec39d2cd88dac2e7cdbac248762f1f057971c5d upstream.
The driver uses pcim_enable_device() to enable the PCI device, the device will be automatically disabled on driver detach through the managed device framework. The manual pci_disable_device() calls in the error paths are therefore redundant and should be removed.
Found via static anlaysis and this is similar to commit 99ca0b57e49f ("thermal: intel: int340x: processor: Fix warning during module unload").
