Hello, We are a student group and we want to contribute to the linux kernel. We are thinking in put effort to move a driver from staging to the main tree. We looked into three drivers: * adc/ad7780.c * adc/ad7816.c * impedance-analyzer/ad5933.c Are these drivers still being worked on? The last commit referencing these drivers were on march 2018, but they are still in staging since 2010. We already know that we have to convert from the old api to the new one. It is OK for us to work on this? Is there something else we can do? Thank you
