The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.
Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where
appropriate.

Pass platform_data as an argument to fbtft_framebuffer_alloc()
instead of using dev->platform_data.
This fixes an issue where the device comes from Device Tree
and fbtft_probe_common() sets dev->platform_data to allocated
memory. When the module is reloaded, dev->platform_data points
to freed memory.

I was looking at how TOTAL_CAM_ENTRY is used and I saw this code. We
print an error but continue writing "EntryNo" to a register as if it
were valid. "EntryNo" is controlled by the user in rtl8192_ioctl() so
it definitely can be invalid. I'm not positive what happens with the
invalid data but it can't be good.

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.

Because devdata->enab_dis_acked is the flag used to determine whether an
enable/disable operation to the IO partition has completed, it should
always be cleared prior to initiating the operation. The call added to
visornic_enable_with_timeout() added in this patch makes the usage there
consistent with visornic_disable_with_timeout().
