commit a0aae96be5ffc5b456ca07bfe1385b721c20e184 upstream.
Check for return code from avs_pcm_hw_constraints_init() in avs_dai_fe_startup() only checks if value is different from 0. Currently function can return positive value, change it to return 0 on success.
Reviewed-by: Cezary Rojewski cezary.rojewski@intel.com Signed-off-by: Amadeusz Sławiński amadeuszx.slawinski@linux.intel.com I've observed KASAN on our setups and while patch itself is correct regardless. Problem seems to be caused by recent changes to rates, as this started happening after recent patchsets and doesn't reproduce with those reverted https://lore.kernel.org/linux-sound/20240905-alsa-12-24-128-v1-0-8371948d392... https://lore.kernel.org/linux-sound/20240911135756.24434-1-tiwai@suse.de/ I've tested using Mark tree, where they are both applied and for some reason snd_pcm_hw_constraint_minmax() started returning positive value, while previously it returned 0. I'm bit worried if it signals some potential deeper problem regarding constraints with above changes.
