From: Andreas Kemnade andreas@kemnade.info
commit 3c398f3c3bef21961eaaeb93227fa66d440dc83d upstream.
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.
