[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] Loss of diagnostic precision by downgrading the logging context from tile-level to device-level.
- [Low] The `memirq_err()` macro was left defined in the file despite all its calls being replaced.

--- Patch [5]: [PATCH 05/12] drm/xe/memirq: Report errors using structured xe_log API ---
commit 081cec958cab790284a251bc663834e4569a80b2

drm/xe/memirq: Report errors using structured xe_log API

This patch replaces memirq_err() calls with xe_log_err() using the
MEMIRQ component tag for memory-based IRQ failures.

[Severity: Low]
This isn't a bug, but did you mean to also remove the definition of
the memirq_err() macro at the top of this file? It appears to be
dead code now that all invocations have been replaced.

[Severity: Medium]
Does this change lose diagnostic precision by downgrading the logging
context from tile-level to device-level?

By explicitly passing the xe device instead of the available tile
variable, the location type resolves to the device, omitting the
specific failing tile ID from the structured log.

[Severity: Medium]
Similarly, does passing memirq_to_xe(memirq) here instead of resolving
the tile or GT lose subsystem context for this log message?
