Subject: staging: comedi: use unsigned sample in cfc_write_to_buffer()
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ca05b81334f46469c6eb4ba7cf8630f3143c22e5;p=deliverable%2Flinux.git

staging: comedi: use unsigned sample in cfc_write_to_buffer()

Sample values in comedi are generally represented as unsigned values.
`cfc_write_to_buffer()` in "comedi_fc.h" currently uses `short` to hold
a 16-bit sample value to be written to the buffer.  Change the type of
the parameter to `unsigned short` for consistency.
