Hi Jonathan,

Sorry for the inconvenience, we updated the git url to 
https://kernel.googlesource.com/pub/scm/linux/kernel/git/jic23/iio.git 
recently,
but it seems the branches are not updated, so we switch to use 
https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio.git now.

Best Regards,
Rong Chen
