From 141670e9b4356b59b5b39a99e10ac0118d12b16d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 5 Apr 2012 21:35:15 +0300 Subject: [PATCH] drm: Move drm_format_num_planes() to drm_crtc.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There will be a need for this function in drm_crtc.c later. This avoids making drm_crtc.c depend on drm_crtc_helper.c.
