Subject: [PATCH 2/2] drm/msm/adreno: Use generic function to load firmware to a buffer object
Date: Thu,  1 Feb 2018 12:15:17 -0700	[thread overview]
Message-ID: <1517512517-31166-3-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1517512517-31166-1-git-send-email-jcrouse@codeaurora.org>

Move a5xx specific code to load firmware into a buffer object to
the generic Adreno code. This will come in useful for future targets.
