[why] Rename hw_sequencer to hwseq. Move all hwseq files to unique folder hwss. [how] creating hwss repo in dc, and moved the dcnxx_hwseq.c and .h files into corresponding new folders inside the hwss and cleared the linkage errors by adding relative paths in the Makefile.template.

drm/amd/dc/dce120: Fix audio register mapping, stop triggering KASAN

2022-11-23T14:01:53+00:00

There's been a very long running bug that seems to have been neglected for a while, where amdgpu consistently triggers a KASAN error at start: BUG: KASAN: global-out-of-bounds in read_indirect_azalia_reg+0x1d4/0x2a0 [amdgpu] Read of size 4 at addr ffffffffc2274b28 by task modprobe/1889 After digging through amd's rather creative method for accessing registers, I eventually discovered the problem likely has to do with the fact that on my dce120 GPU there are supposedly 7 sets of audio registers. But we only define a register mapping for 6 sets. So, fix this and fix the KASAN warning finally.
