after unbinding mmc I get things like this:
[ 185.294067] mmc1: card 0001 removed
[ 185.305206] omap_hsmmc
480b4000.mmc: wake IRQ with no resume: -13
The wakeirq stays in /proc-interrupts
rebinding shows this:
[ 289.795959] genirq: Flags mismatch irq 112.
0000200a (
480b4000.mmc:wakeup) vs.
0000200a (
480b4000.mmc:wakeup)
[ 289.808959] omap_hsmmc
480b4000.mmc: Unable to request wake IRQ
[ 289.815338] omap_hsmmc
480b4000.mmc: no SDIO IRQ support, falling back to polling
That bug seems to be introduced by switching from devm_request_irq()
to generic wakeirq handling.
So let us cleanup at removal.
