nvkm test builds fail with the following error.
drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:
In function 'nvkm_control_mthd_pstate_info':
drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:60:35: error:
overflow in conversion from 'int' to '__s8' {aka 'signed char'}
changes value from '-251' to '5'
The code builds on most architectures, but fails on parisc where ENOSYS
is defined as 251. Replace the error code with -ENODEV (-19). The actual
error code does not really matter and is not passed to userspace - it
just has to be negative.
