I could imagine treating both gpio-virtuser and this code as
a gpiolib extension rather than a consumer (which is usually
part of some other subsystem's driver).

It would also make sense to me to separate gpio providers
from gpiolib in a way, moving one or both of them into a
subdirectory of drivers/gpio/.

It's probably not worth the pain of moving files, but at
least in Kconfig and filenames, they could be named
gpiolib-virtuser.c and gpiolib-sloppy-logic-analyzer.c
to make it clear that these are not gpio provider drivers
but something else, more along the lines of gpiolib-cdev.c
and gpiolib-sysfs.c.
