Subject: staging: comedi: dt3000: sample types are unsigned
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=37a96e994c31b4ad823861f9858dbdf52ef801a6;p=linux-beck.git

staging: comedi: dt3000: sample types are unsigned

Sample values in comedi are generally represented as unsigned values.
Change the type of the `data` variable in `dt3k_ai_empty_fifo()` from
`short` to `unsigned short` for consistency.
