Subject: [PATCH AUTOSEL 6.10 095/197] ASoC: Intel: boards: always check the result of acpi_dev_get_first_match_dev()
From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.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.
