From b70c2cf95ee1ca2806cb7191504920f8f5b4454e Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Mon, 3 Apr 2023 14:33:48 -0700 Subject: cxl/hdm: Skip emulation when driver manages mem_enable If the driver is allowed to enable memory operation itself then it can also turn on HDM decoder support at will. With this the second call to cxl_setup_hdm_decoder_from_dvsec(), when an HDM decoder is not committed, is not needed.
