| | | | | | | | | | | | | | | This is a big cleanup of return types across a number of modules in the nvgpu driver. Many functions were returning u32 but using negative return codes. This is a MISRA 10.3 violation by assigning signed values to a u32.

| | | | | | | | | | | | | | | | | | | Put all debugfs dependencies inside #ifdef CONFIG_DEBUG_FS. This includes some functions in allocators that were used only for debugging. Remove include of linux/debugfs.h on files that do not deal with debugfs. linux/debugfs.h implicitly included linux/fs.h, which we relied on. Add explicit include of linux/fs.h for all files where this is the case.
