we do have easier to use

	xe_err(xe, ...)

and also recently added SIGID logs:

	xe_log_err(xe, ...)

which maybe we should consider here?
or is it done by the other layer?

@Mallesh ?

Agree with @Michal

Please use SIGID for err logging. xe_ttm_vram_handle_addr_fault() used in 

handle_page_offline (https://patchwork.freedesktop.org/series/172710/), where all error reporting using SIGID.
