drm/amdgpu: fix the incorrect external id for raven series (7e4545d3) · Commits · 戴 / test

This patch fixes the incorrect external id that kernel reports to user mode driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while rev_id == 1. Reported-by:
