Subject: staging: comedi: das16: remove an unnecessary check in the attach
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3ffb03e62a12d82f7ce1b1aaa471f780e2e42743;p=openwrt%2Fstaging%2Fblogic.git

staging: comedi: das16: remove an unnecessary check in the attach

If the user does not specify the analog output range the private data
'user_ao_range_table' will not be allocated. The comedi core will detect
the NULL s->range_table and automatically set it to &range_unknown.
