6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
When commit 0cab68720598 ("cxl/pci: Fix disabling memory if DVSEC CXL
Range does not match a CFMWS window") was backported, this chunk moved
from the cxl_hdm_decode_init() function which returns negative error
codes to the __cxl_hdm_decode_init() function which returns false on
error. So the error code needs to be modified from -ENXIO to false.
This issue only exits in the 6.1.y kernels. In later kernels negative
error codes are correct and the driver didn't exist in earlier kernels.
