From: Archit Taneja Date: Mon, 30 Jan 2012 05:22:39 +0000 (+0530) Subject: OMAPDSS: Features: Maintain dss_feats as a list X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c124f23dfdf7da890405dfa0efbeb015cab27b56;p=mv-sheeva.git OMAPDSS: Features: Maintain dss_feats as a list The number of dss_feat_id members has increased to a large value, the current way of assigning a subset of these features (for a particular OMAP) as a mask is no longer feasible. Maintain the subset of features supported as lists. Make the function dss_has_feature() traverse through this list.
