SubjectRe: [PATCH 1/1] : hwmon - new chip driver for TI ADS7828 A-D
Andrew,

Thanks your your comments, I'm currently preparing/testing a revised patch based on your suggestions, which I will post later this week.

A couple of comments inline.

OK, I copied one of the other hwmon drivers, many of which are marked experimental.

OK, this is due to re-using the driver structure/style of other hwmon drivers, will try to improve.

Hmmm, this code exists in pretty much all of the other hwmon drivers, so I will leave it in.

I think it relates to I2C vs ISA connected devices, to avoid detecting something with the correct ID on the wrong bus?
