Subsystem:
drm driver for arm pl111 clcd, drm drivers, drm drivers and misc gpu patches, the rest · Maintainers:

Switch to devm_of_reserved_mem_device_init() so the reserved memory region is released automatically on probe failure or device removal. Remove the explicit of_reserved_mem_device_release() calls in the dev_put error path and pl111_amba_remove().
