    ARM: pxa: propagate errors from regulator_enable() to pxamci · a829abf8
    Arnd Bergmann authored
    The em_x270_mci_setpower() and em_x270_usb_hub_init() functions
    call regulator_enable(), which may return an error that must
    be checked.
    
    This changes the em_x270_usb_hub_init() function to bail out
    if it fails, and changes the pxamci_platform_data->setpower
    callback so that the a failed em_x270_mci_setpower call
    can be propagated by the pxamci driver into the mmc core.
