[PATCH] ARM: OMAP2+: Fix a reference leak bug in omap_hwmod_fix_mpu_rt_idx()

[Haoxiang Li]

omap_hwmod_fix_mpu_rt_idx() gets the first child node with
of_get_next_child(), which returns a node with its reference count
incremented. The function uses the child node to translate the MPU
runtime register resource, but never drops the reference afterwards.

Add the missing of_node_put() after of_address_to_resource().

Fixes: 1dbcb97c656e ("ARM: OMAP2+: Fix module address for modules using mpu_rt_idx")
