[PATCH 0/2] ALSA: hda: cs35l56: fix system name leaks

Posted by Cássio Gabriel 4 days, 9 hours ago

cs35l56_hda_read_acpi() reads an allocated ACPI _SUB string to build
the firmware system name. Current error paths can return after _SUB has
been allocated, or after it has been transferred to cs35l56->system_name,
without releasing that memory.

Fix the local read_acpi() unwind paths first, then release the stored
system name from the common probe error path.
