Subject: caif-hsi: Remove wake line modification when flushing FIFO
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1e226773c7e79051aa8a48258fe6ae61d20332bf;p=openwrt%2Fstaging%2Fblogic.git

caif-hsi: Remove wake line modification when flushing FIFO

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.
