7.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Pratik Vishwakarma <[email protected]> commit 52075128273ace53e6254e37899a47d40d4baf45 upstream. Family 0x1a, model 0xd0..0xd7 belongs to the Zen5 generation. Carve it out from the larger, Zen6 range where former doesn't belong.
