Subsystem:
arm mali-c55 isp driver, media input infrastructure (v4l/dvb), the rest · Maintainers:
Daniel Scally, Jacopo Mondi, Mauro Carvalho Chehab, Linus Torvalds
Use the devres-managed devm_of_reserved_mem_device_init() instead of the manual of_reserved_mem_device_init()/of_reserved_mem_device_release() pair, letting the device resource manager handle cleanup automatically.
