Subject: [PATCH] PCI: vmd: Fix two issues reported by Smatch
Date: Thu, 20 Apr 2023 16:19:57 +0800 [thread overview]
Message-ID: <20230420081957.1440423-1-korantwork@gmail.com> (raw)
From: Xinghui Li <korantli@tencent.com>
There is one uninitialized symbol error reported by smatch:
"drivers/pci/controller/vmd.c:931 vmd_enable_domain()
error: uninitialized symbol 'ret'."
Fix it by assigning ret with pci_reset_bus return.
And one inconsistent indenting warning:
"drivers/pci/controller/vmd.c:1058 vmd_resume()
warn: inconsistent indenting"
Fix it by formating its indenting.
Fixes: 0a584655ef89 ("PCI: vmd: Fix secondary bus reset for Intel bridges")
Fixes: d899aa668498 ("PCI: vmd: Disable MSI remapping after suspend")
