Christophe Jaillet proposed to complete the exception handling also for th=
is
function implementation.
I find that such a software correction is qualified for this tag.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Do=
cumentation/process/submitting-patches.rst?id=3De99332e7b4cda6e60f5b5916cf=
9943a79dbef902#n183

Corresponding consequences can vary then according to the change managemen=
t
of involved developers.

I can agree to this view (in principle).

By the way:
The referenced commit contains the tag =E2=80=9CFixes=E2=80=9D.

> Your suggestion, 'free_dma' is also good.

Thanks for your positive feedback.

But the change acceptance can occasionally become harder.

I imagine that some alternatives can result in preferable solutions, can't=
 they?
