Subject: [PATCH net-next 1/4] caif-hsi: Remove wake line modification when flushing FIFO

From: Christian Auby <christian.auby@...ricsson.com>

Raising wake before flushing FIFO and lowering it after caused a
spike on AC wake that were sometimes detected and acted upon by the
modem. Fixed this by remove wake line modification when flushing FIFO.
