Subject: net: wwan: t7xx: bug: mtk_t7xx not working on my arm development
 version works stably

I'm going to start by putting out two reports from dmesg's journal.

This is the complete log of the first boot up of the ARM platform
development board.

The main problem with this log is that when I just connect to the
internet the kernel log shows ‘[ 145.531887] mtk_t7xx 0000:01:00.0:
CLDMA0 queue 5 is not empty
[ 273.561922] NOHZ tick-stop error: local softirq work is pending,
handler #08!!!’ and the speed is unstable

This log is after the development board performs a reboot.

The main problem is that wwan0at0 and wwan0mbim0 cannot be generated properly.
