Subject: [PATCH v1 1/2] iommu/vt-d: convert the return type of first_pte_in_page to bool
Date: Wed, 15 Sep 2021 23:21:28 +0800	[thread overview]
Message-ID: <20210915152129.1254-2-longpeng2@huawei.com> (raw)
In-Reply-To: <20210915152129.1254-1-longpeng2@huawei.com>

first_pte_in_page() returns boolean value, so let's convert its
return type to bool.
