The if and the else branch code are identical - so the condition has no
effect on the effective code - this patch removes the condition and the
duplicated code.

v2: Review notes from Ian Abbott <abbo...@mev.co.uk> and Hartley Sweeten 
    <hartl...@visionengravers.com> confirm that the condition is not 
    needed and, as suggested, the misleading comment is completely removed.

Patch was only compile tested for x86_64_defconfig + CONFIG_STAGING=y
CONFIG_COMEDI=m, COMEDI_ISA_DRIVERS=y, CONFIG_COMEDI_DT282X=m

Patch is against 3.19.0-rc7 (localversion = -next-20150204)
