Subject: [PATCH AUTOSEL 5.18 09/68] tty: Fix a possible resource leak in icom_probe
From: Huang Guobin <huangguobin4@...wei.com>
[ Upstream commit ee157a79e7c82b01ae4c25de0ac75899801f322c ]
When pci_read_config_dword failed, call pci_release_regions() and
pci_disable_device() to recycle the resource previously allocated.
