From 4aab3fadad32ff4df05832beff7c16fd6ad938aa Mon Sep 17 00:00:00 2001 From: Laxman Dewangan Date: Tue, 13 Nov 2012 19:33:58 +0530 Subject: mfd: tps65910: Move interrupt implementation code to mfd file In place of implementing the irq support in separate file, moving implementation to main mfd file. The irq files only contains the table and init steps only and does not need extra file to have this only for this purpose.
