From 729377d559607ea40d714e8f7092f40f643cf01f Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Wed, 11 Sep 2013 14:23:09 -0700 Subject: [PATCH] pnp: change pnp bus pm_ops to invoke pnp driver dev_pm_ops if specified MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from pnp_driver. Changed pnp_bus_suspend() and pnp_bus_resume() to check if pnp driver has dev_pm_ops and call. If dev_pm_ops don't exist, then call use legacy pm_ops. Without this change, pnp_driver dev_pm_ops will not get called. In addition to the pnp driver bus pm_ops change to invoke driver dev_pm_ops, this patch set contains changes to rtc-cmos, tpm_tis, and apple-gmux pnp drivers to convert from legacy pm_ops to dev_pm_ops. This patch (of 4): pnp_bus_suspend() and pnp_bus_resume() invoke legacy pm_ops from pnp_driver. Changed pnp_bus_suspend() and pnp_bus_resume() to check if pnp driver has dev_pm_ops and call. If dev_pm_ops don't exist, then call use legacy pm_ops. Without this change, pnp_driver dev_pm_ops will not get called.
