ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41_get_acpi_mute_state()
Details

In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda: cs35l41: Fix NULL pointer dereference in cs35l41getacpimutestate()

Return value of a function acpievaluatedsm() is dereferenced without checking for NULL, but it is usually checked for this function.

acpievaluatedsm() may return NULL, when acpievaluateobject() returns acpistatus other than ACPISUCCESS, so add a check to prevent the crach.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
