[PATCH v2] staging: comedi: Simplify conditional evaluation

[Deepak R Varma]

Boolean comparison of the condition inside unittest function is
unnecessary and can be simplified by directly using the condition
outcome for evaluation. Issue reported by :
scripts/coccinelle/misc/boolinit.cocci

Changes since v1:
   - Corrected wrongly inverted tests. Feedback from Ian Abbott.
   - Note:
       This patch was sent earlier as part of a patch set containing 2
       patches. The second patch of the patch set is dropped. Hence
       sending this standalone patch as v2 version. This is based on the
       feedback from Ian Abbott and Julia L.

Looks OK to me.  I have a minor quibble about the patch title.  Maybe 
change the tags to "staging: comedi: tests:" to narrow down the scope.
