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.

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.

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).

0e1af73dde staging/wilc1000: use proper naming for global symbols
There are many global symbols in the wilc1000 driver, some of them
with names like "DEBUG_LEVEL" or "probe" that are not acceptable
for globals in the linux kernel as they may easily conflict with other
(equally broken) drivers.

This renames all the globals that do not already start with
wilc or a variation of that to start with wilc_ and to follow
the usual naming conventions.

1608c4034e staging/wilc1000: make symbols static if possible
All symbols that are only referenced in the file that defines
them can be declared 'static' to avoid namespace pollution,
to produce better object code, and to make the source more
readable.
