Null checking wilc_netdev and skb->dev are already done in the begining of the
function and they are just print printing error log, so delete them.
Null checking wilc is needed before is used so add null ckeck before it is

Arnd Bergmann 562ed3f1f7 staging/wilc1000: pass struct wilc to most linux_wlan.c functions
We want to get rid of all global variables in this driver, and
instead pass device structures from one function to another.
This changes the linux_wlan.c and wilc_wlan.c to do this
for the most part. There are a few exceptions where these
functions are themselves called from another part of the driver
that does not have an instance pointer at hand. Changing those
would be a follow-up step.

There are a few other globals that will have to get moved
into struct wilc at a later point.

Arnd Bergmann c94f05ee6b staging/wilc1000: use more regular probing
So far, my patches tried to do equivalent conversions of the
existing code.  This one goes beyond that by restructuring
how the devices get probed. In particular, the spi driver
no longer creates the netdev until the device is probed,
and I've removed the global wilc_sdio_func and wilc_spi_dev
variables in favor of retrieving them from the wilc_dev
variable that will eventually get passed through all functions
instead of using a global.

in wilc_hif_func. We also change arguments slightly to pass the device,
as we are already touching those lines and the change will be needed

Whether the SDIO function uses an internal or external interrupt
should not be a compiletime decision but be determined at runtime.

This changes the code to pass a GPIO number from the init code
as early as possible, and leaves just one #ifdef WILC_SDIO_IRQ_GPIO
to preserve the previous behavior.

All other locations that check for the interrupt method are turned
into runtime checks based on the gpio number (>=0) or the interrupt
number (>0).
