Subject: p54: drop device reference count if fails to enable device
Date: Wed, 17 Apr 2019 17:41:23 +0800	[thread overview]
Message-ID: <> (raw)

The function p54p_probe takes an extra reference count of the PCI
device. However, the extra reference count is not dropped when it fails
to enable the PCI device. This patch fixes the bug.
