Subject: mips: 7segled - convert sysdev_class to a regular subsystem
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0e38eaf34e0d9955aeaaed9648b2cfaba3076fee;p=mv-sheeva.git

mips: 7segled - convert sysdev_class to a regular subsystem

After all sysdev classes are ported to regular driver core entities, the
sysdev implementation will be entirely removed from the kernel.
