[linux-yocto] [PATCH 05/24] mmc: sdhci: Allow for irq being shared

[Darren Hart]

From: Adrian Hunter <adrian.hunter at intel.com>

If the SDHCI irq is shared with another device then the interrupt
handler can get called while SDHCI is runtime suspended.  That is
harmless but the warning message is not useful so remove it.  Also
returning IRQ_NONE is more appropriate.
