When this driver is built as a module, I cannot rmmod it after insmoding it. This is because that this driver calls ravb_mdio_init() at the time of probe, and module->refcnt is incremented by alloc_mdio_bitbang() called after that. Therefore, even if ifup is not performed, the driver is in use and rmmod cannot be performed. $ lsmod Module Size Used by ravb 40960 1 $ rmmod ravb rmmod: ERROR: Module ravb is in use Call ravb_mdio_init() at open and free_mdio_bitbang() at close, thereby rmmod is possible in the ifdown state.
