Subject[PATCH 0/8] staging: comedi: some comedi_write() changes
Tidy up the "write" file operation handler, `comedi_write()` a bit and
improve the error handling.

1) staging: comedi: rearrange comedi_write() code
2) staging: comedi: do extra checks for becoming non-busy for "write"
3) staging: comedi: make some variables unsigned in comedi_write()
4) staging: comedi: avoid bad truncation of a size_t in comedi_write()
5) staging: comedi: allow buffer wraparound in comedi_write()
6) staging: comedi: return error on "write" if no command set up
7) staging: comedi: simplify returned errors for comedi_write()
8) staging: comedi: check for more errors for zero-length write
