From 2368a95b8f100e0b6fdb332a5118fe6e5af12fb6 Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Thu, 29 Oct 2020 14:51:30 +0800 Subject: [PATCH] ucm: return error if boot_list is empty If bootlist is empty, that means there is no BootSequence defined in the ucm for this sound card, let set_boot_user() return error, then alsactl could have chance to use non-ucm ways to initialize the sound card.
