mfd: Clean timberdale error handling code up
Browse files Browse the repository at this point in the history
In the first three cases, ioremap has been called, so iounmap is needed.  A
new label for this is introduced, to differentiate it from err_msix, which
is the first point at which msix_entries actually needs to be freed.
