This patch removes useless local variable, s32Error and returns directly
zero from wilc_wfi_cfgoperations.c and also removes incorrect break in
switch-case statement. The break is not useless which is being called right
after return statement.

This patch removes unused local variables from host_interface.c.
The unused local variable, s32Error is used just to return zero, so this

Staging: rtl8192e: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which
could result from the multiplication of number of elements and size and
it is also a bit nicer to read.
The problem fixed was that the back-end IO partition was holding onto
stale receive buffers after the "rmmod visornic", and erroneously
completing them after a subsequent "modprobe visornic". This is fixed
in this patch as follows:
* Tell the back-end IO partition that we want it to employ its
"incarnation mechanism" to ensure it does not complete stale receive
buffers after the guest virtual device environment changes (e.g., by
re-loading the driver), by setting the
ULTRA_IO_DRIVER_SUPPORTS_ENHANCED_RCVBUF_CHECKING feature bit, and
supplying a unique incarnation number in rcvpost.unique_num for each
receive buffer posted.
* When visornic loads, make sure we drain and ignore any possible-stale
data in the channel before beginning network operation.
Prior to this patch, faults like this would occur almost every time if
you attempted to rmmod + modprobe the visornic driver and restart the
network service during heavy network activity:
