Subject: staging: comedi: s626: remove unnecessary variable initialization
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ea2e3182686e2df95e432fdaae66d6b0d1547720;p=deliverable%2Flinux.git

staging: comedi: s626: remove unnecessary variable initialization

We initialize 'irqbit' to 0, only to properly set it immediately
afterwards.  Just remove the zero-initialization.
