Subject: ALSA: hda: make kobj_type structure constant
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=aacdac35b906e476b175a8ffc057165eca563076;p=linux.git

ALSA: hda: make kobj_type structure constant

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.

Take advantage of this to constify the structure definition to prevent
modification at runtime.
