Comment 1 Bastien Nocera 2015-10-02 12:36:44 UTC 
genirq: Flags mismatch irq 0. 00000080 (mmc0) vs. 00002001 (Crystal Cove)

That would be:
MMC0 flags = IRQF_SHARED
and
Crystal Cove flags = IRQF_ONESHOT | IRQF_TRIGGER_RISING
Comment 2 Bastien Nocera 2015-10-02 12:43:53 UTC 
CONFIG_GPIO_CRYSTAL_COVE=y is set in the config.
Comment 3 Bastien Nocera 2015-10-05 20:06:38 UTC 
Looks fixed in newer kernels.
