Subject: [PATCH 11/33] efi/gop: Use helper macros for populating lfb_base
Date:   Fri, 24 Apr 2020 15:05:09 +0200
Message-Id: <20200424130531.30518-12-ardb@kernel.org>
In-Reply-To: <20200424130531.30518-1-ardb@kernel.org>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Arvind Sankar <nivedita@alum.mit.edu>

Use the lower/upper_32_bits macros from kernel.h to initialize
si->lfb_base and si->ext_lfb_base.
