Subject: [PATCH AUTOSEL 6.11 111/244] ASoC: Intel: boards: always check the result of acpi_dev_get_first_match_dev()
Date: Wed, 25 Sep 2024 07:25:32 -0400	[thread overview]
Message-ID: <20240925113641.1297102-111-sashal@kernel.org> (raw)
In-Reply-To: <20240925113641.1297102-1-sashal@kernel.org>

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 14e91ddd5c02d8c3e5a682ebfa0546352b459911 ]

The code seems mostly copy-pasted, with some machine drivers
forgetting to test if the 'adev' result is NULL.

Add this check when missing, and use -ENOENT consistently as an error
code.
