'devm_kasprintf' is less verbose than:
snprintf(NULL, 0, ...);
devm_kzalloc(...);
sprintf
so use it instead.

Hi,
I got a:
<aviad.krawczyk@huawei.com>: host huawei.com[103.218.216.136] said: 550
5.1.1 Error: invalid recipients is found from 80.12.242.127
However, MAINTAINERS has:
HUAWEI ETHERNET DRIVER
M: Aviad Krawczyk <aviad.krawczyk@huawei.com>
L: netdev@vger.kernel.org
S: Supported
F: Documentation/networking/hinic.txt
F: drivers/net/ethernet/huawei/hinic/
I don't know how this should be fixed (neither if it should be...), so if s.o. knows, please do.
Best regards,
Christophe Jaillet

Maybe this person would know, since he is also from Huawei and has signed
off on a patch by Aviad Krawczyk:
