net: qca_spi: Make sure the QCA7000 reset is triggered
[ Upstream commit 711c62dfa6bdb4326ca6c587f295ea5c4f7269de ] In case the SPI thread is not running, a simple reset of sync state won't fix the transmit timeout. We also need to wake up the kernel thread. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Fixes: ed7d42e24eff ("net: qca_spi: fix transmit queue timeout handling") Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
