Subject: [PATCH 10/12] net: qca_spi: Make sure the QCA7000 reset is triggered
Git-commit: 711c62dfa6bdb4326ca6c587f295ea5c4f7269de
Patch-mainline: v4.18-rc6
References: git-fixes

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.
