Subject: staging:iio: implement an iio_info structure to take some of the constant elements... 
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6fe8135f;p=linux-beck.git

staging:iio: implement an iio_info structure to take some of the constant elements out of iio_dev.

This was suggested by Arnd Bergmann,  Other elements may well
move in here in future, but it definitely makes sense for these.
