To clarify Alexander's reply, there's some guidance on writing commit
messages in section 2 of:

Documentation/process/submitting-patches.rst

The basic idea is that the commit message should make sense on its own,
even if you can't see the diff. Describe the problem first, any
caveats, then the solution taken (in the imperative tense).

e.g. the above could be:

----
Some of the comments in the kernel events code use articles incorrectly,
'a' for words beginning with a vowel sound, where 'an' should be used.
This is somewhat jarring for native speakers reading the comments.

Fix these comments to use 'an' appropriately.
----

The diff looks sound, so FWIW:

Acked-by: Mark Rutland <mark.rutland@xxxxxxx>

Thanks,
Mark.
