* gpu: nvgpu: Cleanup '\n' usage in allocator debuggingAlex Waterman2018-01-25
| | | | | | | | | | | | | | | | | | These '\n' were leftover from the previous debugging macro usage which did no add the '\n' automagically. However, once swapped over to the nvgpu logging system the '\n' is added and no longer needs to be present in the code. This did require one extra modification though to keep things consistent. The __alloc_pstat() macro, used for sending output either to a seq_file or the terminal, needed to add the '\n' for seq_printf() calls and the '\n' had to be deleted in the C files.
