Subject: [PATCH v2 03/12] [media] ngene: use defines to identify the demod_type
Date: Sun, 25 Feb 2018 13:31:31 +0100	[thread overview]
Message-ID: <20180225123140.19486-4-d.scheller.oss@gmail.com> (raw)
In-Reply-To: <20180225123140.19486-1-d.scheller.oss@gmail.com>

From: Daniel Scheller <d.scheller@gmx.net>

Make it more clear which demod_type is used for which hardware by having
defines for the possible demod_type values. With that, change the
demod_type evaluation in tuner_attach_probe() to a switch-case instead
of an if() for each possible value.
