The comedi core expects the driver attach functions to return a
negative errno for failure. Any other value indicates success.
For consistency in the drivers, make sure they all return '0' to
indicate success.

The subdev_8255_init() call returns 0 for success of a negative errno for failure.
For aesthetics, change the error test in this driver from (rc < 0) to simply (rc)
to follow the style of the other users of this function.

Handling redirect replies requires both map_sem and request_mutex.
Taking map_sem unconditionally near the top of handle_reply() avoids
possible race conditions that arise from releasing request_mutex to be
able to acquire map_sem in redirect reply case. (Lock ordering is:
map_sem, request_mutex, crush_mutex.)

I was doing some code audits looking at scattergather uses, and noticed
that update() in drivers/staging/rtl8192u/ieee80211/digest.c uses
sg.page which doesn't exist any longer, so this can't possibly compile.
Turns out that digest.c is actually unused. It doesn't get referenced
in a Makefile or get compiled and doesn't get used as far as I can see.
I then widened the search to all the files in the directory. There are
a *bunch* that look unused. I removed all of them, then added them
back one at a time until the driver compiled again.

2) Change it to u8 data instead of short.
3) This means we can memcpy() it to the correct location instead of
using a for loop.
