[PATCH 00/10] drm/bridge: Remove redundant error messages on IRQ request failure

[PATCH 00/10] drm/bridge: Remove redundant error messages on IRQ request failure

[Pan Chuang]

Commit 55b48e23f5c4 ("genirq/devres: Add error handling in
devm_request_*_irq()") added automatic error logging to
devm_request_threaded_irq() and devm_request_any_context_irq()
via the new devm_request_result() helper, which prints device
name, IRQ number, handler functions, and error code on failure.

Since devm_request_irq() is a static inline wrapper around
devm_request_threaded_irq(), it also benefits from this
automatic logging.

Remove the now-redundant dev_err() and dev_err_probe() calls
in drm/bridge drivers that follow these devm_request_*_irq()
functions, as the core now provides more detailed diagnostic
information on failure.

Pan Chuang (10):
  drm/bridge: analogix_dp: Remove redundant dev_err()

Out of curiosity, did you apply using b4?

I see the commit does not have the R-by I gave to the cover letter a few
days ago, and assumed b4 would pick it up as it does when applying the full
series. If my assumption was wrong, maybe it's an issue to report to the b4
project?

Oops, sorry about that. I actually found your response to the cover
later as I continued to work through my inbox backlog, but I had
already pushed the patch. :( I was also surprised that b4 hadn't
picked it up...

I applied w/

b4 am -P_ 20260723131649.134127-11-panchuang@vivo.com

Running it again still doesn't find your review:

$ b4 am -P_ 20260723131649.134127-11-panchuang@vivo.com

Ah, if I don't do the "-P_" then it finds your tags, but I don't know
of a way to pick up just one patch other than that... Even "b4 am -t
-P_" doesn't find your tags... I guess that's by design?
