    ptp_qoriq: fix memory leak in probe()
    
    [ Upstream commit f33642224e38d7e0d59336e10e7b4e370b1c4506 ]
    
    Smatch complains that:
    drivers/ptp/ptp_qoriq.c ptp_qoriq_probe()
    warn: 'base' from ioremap() not released.
    
    Fix this by revising the parameter from 'ptp_qoriq->base' to 'base'.
    This is only a bug if ptp_qoriq_init() returns on the
    first -ENODEV error path.
    For other error paths ptp_qoriq->base and base are the same.
    And this change makes the code more readable.
