Subject: drm/radeon: fix card_posted check for newer asics
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 09fb8bd1a63b0f9f15e655c4fe8d047e5d2bf67a upstream.
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.
