[ Upstream commit 586745f1598ccf71b0a5a6df2222dee0a865954e ]
if of_find_device_by_node() succeed, imx_suspend_alloc_ocram() doesn't have a corresponding put_device(). Thus add a jump target to fix the exception handling for this function implementation.
Fixes: 1579c7b9fe01 ("ARM: imx53: Set DDR pins to high impedance when in suspend to RAM.")
