Subject[PATCH 02/36] mips: convert vpe_class to use dev_groups
Date
The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the MIPS vpe_class code to use
the correct field.

Ralf, feel free to apply this to your tree, or ACK it and I can take it through
mine.
