[ Upstream commit 334dc5fcc3f177823115ec4e075259997c16d4a7 ]
For default policy, driver will issue an RMA event when the number of
bad pages is greater than 8 physical rows, rather than reaches 8
physical rows, don't rely on threshold configurable parameters in
default mode.

drm/amdgpu: simplify return statement in amdgpu_ras_eeprom_init2024-12-18T17:16:05ZDheeraj Reddy Jonnalagadda2024-12-12T10:56:24Zurn:sha1:69b54d7c7c9435462322e451207a0de9b3409751
Remove the logically dead code in the last return statement of
amdgpu_ras_eeprom_init. The condition res < 0 is redundant since
res is already checked for a negative value earlier. Replace
return res < 0 ? res : 0; with return 0 to improve clarity.

drm/amdgpu: correct the calculation of RAS bad page2024-12-10T15:26:51ZTao Zhou2024-11-29T08:52:41Zurn:sha1:ae756cd8536923841b45340f7ee369272c9bf105
After the introduction of NPS RAS, one bad page record on eeprom may be
related to 1 or 16 bad pages, so the bad page record and bad page are
two different concepts, define a new variable to store bad page number.

Init function is for ras table header read and check function is
responsible for the validation of the header. Call them in different
stages.
