Subject: [alsa-devel] [PATCH AUTOSEL 4.4 002/174] ALSA: hda: fix unused variable warning
Date: Thu, 16 Jan 2020 12:39:59 -0500
Message-ID: <20200116174251.24326-2-sashal@kernel.org> (raw)
In-Reply-To: <20200116174251.24326-1-sashal@kernel.org>

From: Anders Roxell <anders.roxell@linaro.org>

[ Upstream commit 5b03006d5c58ddd31caf542eef4d0269bcf265b3 ]

When CONFIG_X86=n function azx_snoop doesn't use the variable chip it
only returns true.

sound/pci/hda/hda_intel.c: In function ‘dma_alloc_pages’:
sound/pci/hda/hda_intel.c:2002:14: warning: unused variable ‘chip’ [-Wunused-variable]
  struct azx *chip = bus_to_azx(bus);
              ^~~~

Create a inline function of azx_snoop.

Fixes: a41d122449be ("ALSA: hda - Embed bus into controller object")
