I think that something like
if (IS_ERR(e))
{
<+...
*dev_err(...)

would be more appropriate. Whether there is a return or not doesn't
really matter.

I have no idea what you consider "the relevant function name" to be. If
it is always devm_ioremap_resource then it would seem that it does not
need to be dynamically determined.
