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

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. Signed-off-by: Ludovic Desroches --- Hi, Since I had no feedback on this topic: http://permalink.gmane.org/gmane.linux.kernel.mmc/35160 I would like
