RE: [PATCH] pm: print the name of failed suspend function forplatform device

[Liu, Chuansheng]

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
