drivers: staging: wilc1000: use 'void' for no arguments functions
Added 'void' keyword in the paranthesis of function definitions, when
there are no arguments to the functions. This fixes the checkpatch.pl
error - "Bad function definition 'function()' should probably be
function(void)".

Staging: wilc1000: Remove typedefs for struct
The Linux kernel coding style guidelines suggest not using typedefs for
structure and enum types. This patch gets rid of the typedefs for
Ack_session_info_t.
The following Coccinelle semantic patch detects the cases for struct type:
Ever since daemonize was removed in 3.18, there are no longer

Card configuration is stored in SPI EEPROM (93c46 or 93c56)
working in 128|256x16 mode.
Communication is handled using GPIO bitbang.
>From behaviour perspective, delay after read was removed.
It is not needed as we wait after reading GPIO mapped to
PCI-E register - it should have no side effects.
According to sample EEPROM datasheet (AT93Cx6), max frequency for
worst case scenario (1.8V supply) is 250kHZ (vs. 1MHz for 5V).
Driver generates ~50kHZ clock - margin should be big enough
even for devices from other vendors.

staging: unisys: visornic_resume needs to mirror _serverdown_complete
Previously we simplified the serverdown function to basically turn it
into a dev_close(), but missed the analogous logic in visornic_resume()
(which is essentially the "book-end" of visornic_serverdown_complete()).
As a result, during IO partition recovery, the nic would go closed when
the IO partition went away, but would never be opened again when the IO
partition came back.
This patch changes visornic_resume() to use dev_open(), so that it once
again plays nicely with visornic_serverdown_complete(). Because
dev_open() forces us into the visornic_open() path, other logic in
visornic_resume() was no longer necessary, and lended to simplifying
visornic_resume() even more.
