Really?

It is desirable to detect a failed function call, isn't it?

1. Please choose an imperative wording for an improved change description.
   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?h=v6.10-rc4#n94

2. Would you like to add any tags (like “Fixes” and “Cc”) accordingly?

3. How do you think about to append the text “() in axi_dmac_probe()”
   to the summary phrase?

Regards,
Markus
