Subject: [PATCH v7 09/10] arm64: efi: Export screen_info
Date: Mon, 24 Aug 2020 09:46:22 -0700	[thread overview]
Message-ID: <1598287583-71762-10-git-send-email-mikelley@microsoft.com> (raw)
In-Reply-To: <1598287583-71762-1-git-send-email-mikelley@microsoft.com>

The Hyper-V frame buffer driver may be built as a module, and
it needs access to screen_info. So export screen_info.
