[RFC PATCH] mmc: sdhci-of-at91: don't put device in suspend after probe

From: Ludovic Desroches

By putting the device in suspend at the end of the probe, it is
impossible to wake up on non software event such as card
insertion/removal.

Hi,

Since I had no feedback on this topic:
http://permalink.gmane.org/gmane.linux.kernel.mmc/35160

I would like to no more put the device in suspend at the end of the probe. If
my device is suspended at the end of the probe, I have no issue to resume on
a software event such as mounting my sdcard but hardware event such as card
insertion and removal do not trigger a resume.

It seems there are only two sdhci drivers using runtime pm so maybe nobody has
noticed this issue.

Regards

Ludovic
