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. • https://git.kernel.org/stable/c/7f4399ba405b6201fb318b43091703a34b1489ab •
