Subject: net/usb: initiate sync sequence in sierra_net.c driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6f1464bf65fcaa57a4b32dae93de4e8bbdfaf7c5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

net/usb: initiate sync sequence in sierra_net.c driver

The following patch adds the initiation of the sync sequence to
"sierra_net_bind()". If this step is omitted, the modem will never sync up
with the host and it will not be possible to establish a data connection.
