From 9a20332ab373b1f8f947e0a9c923652b32dab031 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 23 Nov 2018 18:18:30 +0100 Subject: ALSA: sparc: Fix invalid snd_free_pages() at error path Some spurious calls of snd_free_pages() have been overlooked and remain in the error paths of sparc cs4231 driver code. Since runtime->dma_area is managed by the PCM core helper, we shouldn't release manually. Drop the superfluous calls.
