Subject: [PATCH 1/1] drivers: staging: comedi: drivers: ni_mio_common.c: removed no-effect right hand operand
Date: Tue, 12 May 2015 21:53:53 -0700 [thread overview]
Message-ID: <1431492833-14711-1-git-send-email-tolga.ceylan@gmail.com> (raw)
In ni_ai_cmd() bitwise or construction of ai_trig in case of TRIG_NOW
is faulty. Register address is accidentally in the expression,
but this has no effect. This is an accidental left-over code
that used to call a function with register address as one of
the arguments.
