Subject: [PATCH 1/2] drm/radeon: fix card_posted check for newer asics
Date: Wed, 22 May 2013 11:32:55 -0400 [thread overview]
Message-ID: <1369236776-19306-1-git-send-email-alexdeucher@gmail.com> (raw)
From: Alex Deucher <alexander.deucher@amd.com>
Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.
