From 7704c095230e2e9863f3aacd0489a4b4cc00bf45 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 7 Nov 2012 16:35:33 -0700 Subject: [PATCH] ARM: remove struct sys_timer suspend and resume fields These fields duplicate e.g. struct clock_event_device's suspend and resume fields, so remove them now that nothing is using them. The aim is to remove all fields from struct sys_timer except .init, then replace the ARM machine descriptor's .timer field with a .init_time function instead, and delete struct sys_timer.
