My test cases don't seem to trigger this on all Fermi boards, not sure
if they're broken tests or it didn't work until later versions.
GF119 definitely works.

Having a \n in the middle of a format string means that the next line
doesn't get the prefixes unlike every other line printed by the trace.

It's really confusing for NV_DEBUG's printing to be controlled via
drm.debug while everything else is controlled via nouveau.debug. These
messages can be turned on with nouveau.debug=DRM=debug.

The hdmi device is required for runtime pm. However it is not available
on many esp older devices, which were all seeing these error messages.
Take this opportunity to also convert to nv_debug instead of the DRM_*
messages, like the rest of nouveau does.

Memory was always allocated for 4096 channels. Change this to allocate
what we actually need according to the number of channels we use.

pm_runtime_get*() may return -EACCES to indicate a device does not have
runtime PM enabled. This is currently the case with platform devices
on Nouveau, and is not an error in that context. Handle this case
without failure.

abi16->handles is a u64, so make sure to use 1ULL << val when modifying.

The ffsll function is a lot slower than the __ffs64 built-in which
compiles to a single instruction on 64-bit. It's also nice to avoid
custom versions of standard functions. Note that __ffs == ffs - 1.

The usage of strict_strtol() is not preferred, because
strict_strtol() is obsolete. Thus, kstrtol() should be
used.
