Subject: Input: serio - make serio_bus const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fbd5f5008fab2203fa21e82579b9b48a7256b8fd;p=linux.git

Input: serio - make serio_bus const

Now that the driver core can properly handle constant struct bus_type,
move the serio_bus variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
