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.
