Subject: [PATCH] ASoC: hdac_hdmi: remove always false condition
Date: Tue, 24 Nov 2015 16:42:26 +0530	[thread overview]
Message-ID: <1448363546-31193-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)

hdac->num_nodes is unsigned int and can never be less than 0.

Signed-off-by: Sudip Mukherjee <sudip@vectorindia.org>

Or, maybe, another way can be to declare num_nodes as int. Then this
test makes sense and also snd_hdac_get_sub_nodes() is returning an int.
