Subject: [PATCH 1/9] drm: Remove unused arg from drm_fb_helper_init
Date: Mon,  2 Mar 2020 18:26:41 +0530	[thread overview]
Message-ID: <20200302125649.61443-2-pankaj.laxminarayan.bharadiya@intel.com> (raw)
In-Reply-To: <20200302125649.61443-1-pankaj.laxminarayan.bharadiya@intel.com>

The max connector argument for drm_fb_helper_init() isn't used anymore
hence remove it.

All the drm_fb_helper_init() calls are modified with below sementic
patch.

-  drm_fb_helper_init(E1,E2, E3)
+  drm_fb_helper_init(E1,E2)
