Subject: drm/armada: use number of CRTCs registered
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d016540722bb412ffa8376a9db0de757ce915bfb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/armada: use number of CRTCs registered

Use the number of CRTCs registered to size the vblank arrays rather than
our own count.  Number CRTCs using this as well.  This permits us to
register CRTCs as components in the near future rather than as part of a
single device.
