From 2b39535b9e54888649923beaab443af212b6c0fd Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Fri, 20 May 2011 15:47:40 +0300 Subject: [PATCH] ASoC: core: Don't set "(null)" as a driver name Commit 22de71b ("ASoC: core - allow ASoC more flexible machine name") writes "(null)" to driver name string in struct snd_card if card->driver_name is NULL. This causes segmentation faults with some user space ALSA utilities like aplay and arecord. Fix this by using the card->name if no driver name is specified.
