drm/nouveau/nvkm: Replace -ENOSYS with -ENODEV
commit e8f71f89236ef82d449991bfbc237e3cb6ea584f upstream.
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.
Fixes: 7238eca4cf18 ("drm/nouveau: expose pstate selection per-power source in sysfs")
