4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Stefan Wahren <stefan.wahren@xxxxxxxx>
[ Upstream commit b2bab426dc715de147f8039a3fccff27d795f4eb ]
As long as the synchronization with the QCA7000 isn't finished, we
cannot accept packets from the upper layers. So let the SPI thread
enable the TX queue after sync and avoid unwanted packet drop.
