From 711c62dfa6bdb4326ca6c587f295ea5c4f7269de Mon Sep 17 00:00:00 2001 From: Stefan Wahren Date: Wed, 18 Jul 2018 08:31:44 +0200 Subject: [PATCH] net: qca_spi: Make sure the QCA7000 reset is triggered 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 Fixes: ed7d42e24eff ("net: qca_spi: fix transmit queue timeout handling") Signed-off-by: David S.
