Subject: [PATCH v2 2/2] MdeModulePkg/UfsPciHc: Avoid overriding return value in BindingStart
Date: Mon, 24 Apr 2017 13:58:37 +0800	[thread overview]
Message-ID: <20170424055837.8624-3-hao.a.wu@intel.com> (raw)
In-Reply-To: <20170424055837.8624-1-hao.a.wu@intel.com>

In function UfsHcDriverBindingStart(), the return value 'Status' may be
overridden during the original PCI attributes restore process.

This commit refines the logic to avoid such override.
