| |
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: "Du, Alek" <alek.du@intel.com>
commit f086ced17191fa0c5712539d2b680eae3dc972a1 upstream.
FCS could be GSM0_SOF, so will break state machine...
[This byte isn't quoted in any way so a SOF here doesn't imply an error occurred.]
