Re: [PATCH] USB and Driver Core patches for 2.6.10

[Greg KH <greg@kroah.com>]

ChangeSet 1.1938.444.28, 2004/12/21 16:51:39-08:00, jbarnes@engr.sgi.com

[PATCH] driver core: allow struct bin_attributes in class devices

This small patch adds routines to create and remove bin_attribute files
for class devices.  One intended use is for binary files corresponding to
PCI busses, like bus legacy I/O ports or ISA memory.
