For the record, I'm still uncomfortable with the name - why not just
spell out your whole name?

Sorry for missing this earlier, but it looks like this patch only
modifies the nb7vpq904m driver, so I think you should specify that
already in the subject.
While at it, you could also specify the only function that is being
modified in the commit message (this is just a suggestion):

        usb: typec: nb7vpq904m: Remove uneeded indentation

        In function nb7vpq904m_parse_data_lanes_mapping(), the "if
        (ep)" condition is basically the entire function. Making the
        code a bit more readable by inverting the condition so that
        the function returns immedately if there is no "ep".

thanks,
