X-Git-Tag: v2.6.32-rc1~684^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3eb132c986f04f64b9c360abd67a1e0d18d6d5b4;p=pandora-kernel.git

PM: Reset transition_started at dpm_resume_noirq

transition_started should be set once the preparation of devices for
a PM has started, reset before starting to resume devices. When
resuming devices, kernel calls dpm_resume_noirq then
dpm_resume_end(dpm_resume).  Thus we should reset transition_started
at dpm_resume_noirq.

This patch fixes ACPI warning when resuming from suspend/hibernate:

ACPI: \_SB_.PCI0.IDE1.PRI1.MAS1 - docking
------------[ cut here ]------------
WARNING: at drivers/base/power/main.c:87 device_pm_add+0x8b/0xcc()
Hardware name: OptiPlex 760
Device: acpi
Parentless device registered during a PM transaction

[rjw: Fixed up the changelog.]
