Description

In the Linux kernel, the following vulnerability has been resolved: ptp_qoriq: fix memory leak in probe() 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.
