| Subject: net: qca_spi: Make sure the QCA7000 reset is triggered |
| |
| From: Stefan Wahren <stefan.wahren@i2se.com> |
| |
| [ 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. |
