Subject: [PATCH 2/2] staging: comedi: cb_das16_cs: remove unneeded default case in analog in read
Date: Tue, 26 Jun 2012 10:08:52 -0700 [thread overview]
Message-ID: <201206261008.52962.hartleys@visionengravers.com> (raw)
The default (return -EINVAL) case is not needed when working
out the correct value to set the analog input range. As pointed
out by Ian Abbott, the comedi core checks the range in
comedi_check_chanlist() before calling the insn_read() function.
