04c8970771 drm/nouveau/vfn/r535: Convert comma to semicolon
Replace comma between expressions with semicolons.

Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.

Found by inspection.
No functional change intended.
Compile tested only.

76b8f81a5b drm/nouveau: improve handling of 64-bit BARs
GPUs exist now with a 64-bit BAR0, which mean that BAR1 and BAR2's
indices (as passed to pci_resource_len() etc) are bumped up by one.

Modify nvkm_device.resource_addr/size() to take an enum instead of
an integer bar index, and take IORESOURCE_MEM_64 into account when
translating to the "raw" bar id.

cd3c62282b drm/nouveau/gsp: add usermode class id to gpu hal
Use usermode class ID from nvkm_rm_gpu, instead of copying it from the
non-GSP HALs.
