Hi Ernestas,
the SRT835 is the name of a CPE that is available in more than one
configuration depending on the installed 5G card.
You can not use the CPE name when adding linux driver support, please
find out the type of Meig 5G card (SRMxxx) it is you want to add support
for.
You may have to open up the SRT835 in order to find the name of the
installed 5G card/5G module.
thanks
Lars

Thanks for the update. I removed the changelog when applying (it should
generally go below the --- line so that it does not make it into the
commit message).
I also reworded the first sentence to use imperative mood (see
Documentation/process/submitting-patches.rst).
