[PATCH 02/11] uio: uio_fsl_elbc_gpcm: convert platform driver to use dev_groups

[Greg Kroah-Hartman]

Platform drivers now have the option to have the platform core create
and remove any needed sysfs attribute files.  So take advantage of that
and do not register "by hand" a sysfs group of attributes.
