#     drm/nouveau/nvkm: Replace -ENOSYS with -ENODEV
#     
#     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.
#
