Subject: [PATCH 2/5] drm/i915/bios: Round PCI ROM VBT allocation to multiple of 4
Date: Tue, 10 Sep 2024 16:42:16 +0300 [thread overview]
Message-ID: <20240910134219.28479-3-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20240910134219.28479-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
The SPI code rounds the VBT allocation to a multiple of four bytes
(presumably because it reads the VBT 4 bytes at a time). Do the
same for the PCI ROM side to eliminate pointless differences between
the two codepaths. This will make no functional difference.
