Haotian Zhang cbc8d54c73 clocksource/drivers/ralink: Fix resource leaks in init error path 
[ Upstream commit 2ba8e2aae1 ]

The ralink_systick_init() function does not release all acquired resources
on its error paths. If irq_of_parse_and_map() or a subsequent call fails,
the previously created I/O memory mapping and IRQ mapping are leaked.

Add goto-based error handling labels to ensure that all allocated
resources are correctly freed.
