[PATCH 2/2] ALSA: hda: cs35l56: Free system name on probe errors

[Cássio Gabriel]

cs35l56_hda_read_acpi() stores an allocated firmware system name in
cs35l56->system_name. The normal remove path frees it, but remove is
not called if cs35l56_hda_common_probe() fails after read_acpi() has
succeeded.

Free cs35l56->system_name from the common probe error path and clear
the pointer.
