From 5069e5c93ca73eab185d3bb338a1362275f9ea70 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Tue, 25 Feb 2014 16:37:47 +0200 Subject: [PATCH] ASoC: Intel: sst-acpi: Fix Oops in case of missing firmware I swear I tested missing firmware in commit e5161d7987f1 ("ASoC: Intel: sst-acpi: Request firmware before SST platform driver probing"). Unfortunately same wasn't done in commit 6dda27cbbd1d ("ASoC: Intel: sst-acpi: Add support for multiple machine drivers per platform") which will cause NULL pointer dereference in sst_acpi_fw_cb() when printing the error since sst_acpi->mach is not set. Fix this obvious error by setting the sst_acpi->mach in sst_acpi_probe().
