Subject: [PATCH v2 07/14] efi/gop: Use helper macros for populating lfb_base
Date: Thu, 19 Mar 2020 22:00:21 -0400
Message-ID: <20200320020028.1936003-8-nivedita@alum.mit.edu> (raw)
In-Reply-To: <20200319192855.29876-1-nivedita@alum.mit.edu>

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