From 2035d39da18feba072bb49067b9984454dc4c07b Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Thu, 30 Jan 2014 22:25:05 +0100 Subject: [PATCH] pinctrl: mvebu: remove passing mvebu_mpp_ctrl to callbacks The only valuable information a special callback can derive from mvebu_mpp_ctrl passed to it, is the pin id. Instead of passing the struct, pass the pid directly.
