Subject: [PATCH] bus: mhi: pci-generic: Add missing 'pci_disable_pcie_error_reporting()' calls
Date: Fri, 11 Jun 2021 23:03:50 +0200 [thread overview]
Message-ID: <f70c14701f4922d67e717633c91b6c481b59f298.1623445348.git.christophe.jaillet@wanadoo.fr> (raw)
If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it
must be undone by a corresponding 'pci_disable_pcie_error_reporting()'
call
Add the missing call in the error handling path of the probe and in the
remove function.
Fixes: b012ee6bfe2a ("mhi: pci_generic: Add PCI error handlers")
