media: nuvoton: npcm-video: fix error handling in npcm_video_init() ...
npcm_video_init() has two error handling issues after
of_reserved_mem_device_init() is called:
When dma_set_mask_and_coherent() fails, the function releases the
reserved memory but does not return, allowing execution to fall through
into npcm_video_ece_init() with a failed DMA configuration.
When npcm_video_ece_init() fails, the function returns an error without
calling of_reserved_mem_device_release(), leaking the reserved memory
association.
Fix both by adding the missing return after the DMA mask failure and
adding the missing of_reserved_mem_device_release() call on the ECE init
error path.
