In the Linux kernel, the following vulnerability has been resolved:

soc: microchip: mpfs: Fix memory leak in mpfs sys controller probe()

In mpfs sys controller probe(), if of get mtd device by node() fails, the function returns immediately without freeing the allocated memory for sys controller, leading to a memory leak.

Fix this by jumping to the out free label to ensure the memory is properly freed.

Also, consolidate the error handling for the mbox request channel() failure case to use the same label.
