From b27f8fee4965f42405720097af045a8deebd3bcc Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Sun, 15 Dec 2013 03:14:47 -0800 Subject: [PATCH] Input: pmic8xxx-pwrkey - pass input device directly to interrupt Instead of passing the pointer to the container structure just pass the input device here. This saves a dereference in the fast path.
