Subject: [PATCH] ALSA: echoaudio: Remove redundant check
Git-commit: db091b0e14239f0ebd5709f3f9b5a1d662483adc
Patch-mainline: v5.9-rc1
References: jsc#SLE-16518
This check is always false, as it's not the responsibilty of the
device-specific code to make this check. It is already checked
in snd_echo_digital_mode_put.
I do not have a Mona interface to test this change.
This patch is in preparation for follow-up patch to modify the
behavior of "opencount".
