Subject: [PATCH 5.7 063/163] ALSA: es1688: Add the missed snd_card_free()

From: Chuhong Yuan <hslester96@...il.com>

commit d9b8fbf15d05350b36081eddafcf7b15aa1add50 upstream.

snd_es968_pnp_detect() misses a snd_card_free() in a failed path.
Add the missed function call to fix it.

Fixes: a20971b201ac ("ALSA: Merge es1688 and es968 drivers")
