Subject: staging: comedi: s626: remove boardinfo
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=832defbb58061fedb7a5c43aab7d762afaac2cc9;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

staging: comedi: s626: remove boardinfo

This driver only supports one board type. Move the used board info
out of the boardinfo struct and remove it.
