linux/arch/mips/txx9/generic/setup_tx4939.c
Kay Sievers edbaa603eb driver-core: remove sysdev.h usage. 
The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.
