Description OSIDB Bzimport 2025-10-01 12:03:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

powerpc/52xx: Fix a resource leak in an error handling path

The error handling path of mpc52xx_lpbfifo_probe() has a request_irq()
that is not balanced by a corresponding free_irq().

Add the missing call, as already done in the remove function.
