similar to: drm/nouveau: Checking a kmemdup() call in nouveau_connector_of_detect()

The most common issue on arm is that the pci memory window is too narrow to allocate all the BARs. Can you see if there are messages in the kernel to that effect?

Hi Seeing as we (Raspberry Pi) have just launched the Compute Module 4 with an exposed PCIe x1 lane, people are asking about adding graphics cards. Seeing as you are the people who have the knowledge with regard to NVidia and nouveau, what are your immediate thoughts of nouveau working on ARM/ARM64? Is there a chance of this working? I'm no PCIe expert, although I can call on some expertise

kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memset, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memset. Signed-off-by: Fuqian Huang <huangfq.daxian
