From: Damien Lespiau Date: Wed, 28 May 2014 11:30:56 +0000 (+0100) Subject: drm/i915: Make intel_dsi_init() return void X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4328633d6553558471c260137019c245c2e9d7c6;p=linux-beck.git drm/i915: Make intel_dsi_init() return void Functions that can't fail are such a bliss to work with, it'd be shame to miss the occasion. The "failure" mode is the DSI connector not being created, the rest of the initialization can carry on happily. We weren't even checking that value anyway.
