Subject: RE: [PATCH] pm: print the name of failed suspend function for
 platform device

Hello Greg,

Double checked, there is no your response before.
Can you consider it again? Thanks.

Since we have printed the failure info, why not enhance it a bit:)

Example without this patch:
pm_op(): platform_pm_suspend+0x0/0x50 returns -11
PM: Device power.0 failed to suspend: error -11

And with this patch:
platform_pm_suspend(): power_suspend+0x0/0x30 returns -11
pm_op(): platform_pm_suspend+0x0/0x80 returns -11
PM: Device power.0 failed to suspend: error -11
