From: Imre Deak Date: Mon, 21 Nov 2016 19:15:05 +0000 (+0200) Subject: drm/i915/lspcon: Add dp_to_lspcon helper() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd75f6dd2e7d5de544e8aa8b75d1e50308cd8561;p=linux-beck.git drm/i915/lspcon: Add dp_to_lspcon helper() We need to get to LSPCON in the next patch, so factor out the helper for it. While at it also remove the redundant GEN9 check.
