[PATCH 0/5] drm/{i915, xe}: Refactor generic_handle_irq_safe() error messages

[Jonathan Cavitt]

Currently, all but one uses of generic_handle_irq_safe() report error
messages using .*_err_ratelimited() error reporting helper functions.
These helper functions declare their error messages in the following
form:

"error handling [COMPONENT NAME] irq: %d\n"

.*_err_ratelimited() already logs "error" as a part of the error
message, so declaring the error is redundant.  Reword it.

The last usage of generic_handle_irq_safe() is in xe_i2c_irq_present(),
and it currently lacks the same error reporting as in the other cases.
This is not intentional, so put some logging there.

While we're here, we should also update the XE cases to use
xe_err_ratelimited() instead of directly calling drm_err_ratelimited().
However, mixing drm error reporting functions with xe error reporting
functions in the same file looks unprofessional, so update all drm error
reporting functions in xe_heci_gsc.c and xe_i2c.c to use their xe
counterparts.

This includes updating drm_warn_once() to use xe_warn_once() instead.
Unfortunately, xe_warn_once() does not exist, so create it.

[PATCH 5/5] drm/xe/i2c: Report i2c irq handler issue

[Jonathan Cavitt]

Error logging is expected but not included in xe_i2c_irq_handler() for
generic_handle_irq_safe(), so add error logging there.

This issue was caught by static analysis.

can we print error code in more friendly way using %pe

missing def looks like our coding error, shouldn't we just use xe_assert()?

missing def->name is also our coding error,
we should have no runtime checks for it (except xe_assert)

maybe better message would be:

	"[COMPONENT NAME]: irq handling failed (%pe)\n">

hmm, changing the same line twice in the one series looks weird
can't we change it in the previous patch ?

I think fixing this should be addressed in a different patch series.

I think this also should be addressed in a different patch series.

I can apply the rest of the revision notes, though.
