When I saw this commit I wondered that it was you who told me to think
about this but the commiter was Linus.

Subject: [PATCH] __irq_set_trigger: use %pF to print the set_type callback's name
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

This uses the new feature of printk introduced in
0fe1ef24f7bd0020f29ffe287dfdb9ead33ca0b2.

The actual output is unchanged.
