Have maintainers asked you about this? Otherwise it is irrelevant change.

dev_err() ?

Ditto.

First of all, it's better to decouple assignment and definition, and
move assignment closer to its user. This is usual pattern.

int result;

result = ...
if (result...)

Second, it will look better with standard pattern of checking for errors, i.e.

int result;

if (result < 0)
return;
...
