priv is being explicitly dereferenced when it is still null, when
jumping to goto label err_free_netdev, before it is properly
updated with a valid memory address.

Also, when this happens, memory allocated for netdev at line 854:
netdev = alloc_etherdev(sizeof(*priv)) is not being free'd before
return, hence there is a memory leak.

The current code looks a bit too complicated and can be replaced
by just directly freeing netdev before return.

Notice that card->priv = NULL isn't required because the next thing
we do to card is kfree(card).

ks7010_upload_firmware() is never called in atomic context.

The call chain ending up at ks7010_upload_firmware() is:
[1] ks7010_upload_firmware() <- ks7010_sdio_probe()

ks7010_sdio_probe() is set as ".probe" in struct sdio_driver.
This function is not called in atomic context.

Despite never getting called from atomic context, ks7010_upload_firmware()
calls mdelay() to busily wait.
This is not necessary and can be replaced with usleep_range() to
avoid busy waiting.

This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.
