    pinctrl: enhance reporting of errors when loading from DT · ad6e1107
    John Crispin authored
    There are a few places in the api where the code simply returns -EINVAL when
    it finds an error. An example is pinmux_map_to_setting() which now reports an
    error if we try to match a group with a function that it does not support.
    
    The reporting of errors in pinconf_check_ops and pinmux_check_ops now has the
    same style and is located inside the according functions and not the calling
    code.
    
    When the map is found in the DT but the default state can not be selected we
    get an error to know that the code at least tried.
    
    The patch also removes a stray word from one comment and a "->" from another
    for the sake of consistency.
    
    Finally we replace a few pr_err/debug() calls with dev_err/dbg().
    
    Thanks go to Stephen Warren for reviewing the patch and enhancing the reporting
    inside pinmux_map_to_setting().
