[PATCH] driver core: remove dev_bin_attrs from struct class

From: Greg Kroah-Hartman
Date: Sun Oct 06 2013 - 02:13:13 EST


From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

No in-kernel code is now using this, they have all be converted over to
using the bin_attrs support in attribute groups, so this field, and the
code in the driver core that was creating/remove the binary files can be
removed.
