From 0d542d58b6b5fe01095484c2628e46afe88312a9 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Nov 2018 18:16:33 +0100 Subject: ALSA: wss: Fix invalid snd_free_pages() at error path commit 7b69154171b407844c273ab4c10b5f0ddcd6aa29 upstream. Some spurious calls of snd_free_pages() have been overlooked and remain in the error paths of wss driver code. Since runtime->dma_area is managed by the PCM core helper, we shouldn't release manually. Drop the superfluous calls.
