-Subject: [PATCH] bcm2835-mmc: Fix duplicate free_irq() on remove
-
-The BCM2835 MMC host driver requests its interrupt as a device-managed
-resource, so the interrupt is automatically freed after the driver is
-unbound.
-
-However on driver unbind, bcm2835_mmc_remove() frees the interrupt
-explicitly to avoid invocation of the interrupt handler after driver
-structures have been torn down.
-
-The interrupt is thus freed twice, leading to a WARN splat in
-__free_irq().  Fix by not requesting the interrupt as a device-managed
-resource.
