If anyone has any objections, please let me know. ------------------ From: Tudor Ambarus [ Upstream commit 24fdd5074b205cfb0ef4cd0751a2d03031455929 ] In case of error, of_parse_phandle_with_args() returns -EINVAL when the passed index is negative, or -ENOENT when the index is for an empty phandle. The mailbox core overwrote the error return code with a less precise -ENODEV. Use the error returned code from of_parse_phandle_with_args().
