[ISSUE] ads7828 library is broken currently

I have used the ADS7828 without issues several years ago but today when going back to some previously working code this library is throwing an error

lib/ads7828/i2c_adc_ads7828.cpp:234:1: no return statement in function returning non-void [-Werror=return-type]

messing about with a local copy of the library it appears that there is simply a 'return' missing from the start of line 233 of the file mentioned in the error.

I have no idea how to go about correcting the library. Is this something that one of the admins can fix?

You should just add the return statement and follow the instructions for using a locally modified library. Most of the libraries are community contributed.
