This SmPL construct can be more powerful.

Such an adjustment can be helpful for a few operation modes.

But the number of statements in the if branch will influence the possibility
for the deletion of curly braces together with redundant dev_err() calls
by the SmPL patch mode.

Do other functions share the same error reporting strategy so that any more
collateral software evolution can happen?
