In the Linux kernel, the following vulnerability has been resolved: ptpqoriq: fix memory leak in probe() Smatch complains that: drivers/ptp/ptpqoriq.c ptpqoriqprobe() warn: 'base' from ioremap() not released. Fix this by revising the parameter from 'ptpqoriq->base' to 'base'. This is only a bug if ptpqoriqinit() returns on the first -ENODEV error path. For other error paths ptpqoriq->base and base are the same. And this change makes the code more readable.
