Signed-off-by: Ludovic Desroches <ludovic.desroches@...el.com> --- 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.
