From f377bff0235708ded5f94e581855d6bd678cd2d1 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 8 May 2015 15:22:36 +0200 Subject: [PATCH] can: flexcan: rename feature into quirks This patch renames the "features" member of struct flexcan_devtype_data to "quirks". The corresponding defines are renamed too, to reflect what they actually do.
