[PATCH v2 4/6] drm/rockchip: vop2: use symmetric function pair vop2_{create,destroy}_crtcs

From: Michael Riesch
Date: Thu Jan 19 2023 - 09:42:44 EST


Let the function name vop2_create_crtcs reflect that the function creates
multiple CRTCS. Also, use a symmetric function pair to create and destroy
the CRTCs and the corresponding planes.
