Unwrapped line this time? :-)
ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch24:emac IP-Config: Failed to open eth0 IP-Config: No network devices available The "mismatch" is due to requesting an IRQ that is already in use, while IRQF_PROBE_SHARED wasn't set. However, the real cause is that ravb_close() doesn't release any of the R-Car Gen3-specific secondary IRQs. Add the missing free_irq() calls to fix this.
