staging: vt6656: iwctl: fix up spacing around operators
A few cases were missed in my previous cleanup, this takes care of the
last cases of missing space (or too much space (as in a newline))
around operators ('=', '==', ',', '<').
This patch improves mapping performance in zsmalloc by getting
usage information from the user in the form of a "mapping mode"
and using it to avoid unnecessary copying for objects that span
pages.
This patch replaces the page table assisted object mapping
method, which has x86 dependencies, with a arch-independent
method that does a simple copy into a temporary per-cpu
buffer.
While a copy seems like it would be worse than mapping the pages,
tests demonstrate the copying is always faster and, in the case of
running inside a KVM guest, roughly 4x faster.
zcache is enabled only if one of CONFIG_CLEANCACHE and CONFIG_FRONTSWAP is
enabled, see the Kconfig:
depends on (CLEANCACHE || FRONTSWAP) && CRYPTO=y && X86
So, we can remove the check in the source code

Like most of the comedi drivers, this one appears to have been started

in an unnecessarily complex boardinfo struct.
Remove everything from the boardinfo struct, except the 'name', and
just use the open coded values in the attach function.

the timers to the 'mode'. The cached value is never read or
