The driver's init and exit function don't do anything besides adding and deleting the I2C driver so the module_i2c_driver() macro could be used. Currently is not being used because the driver is initialized at subsys initcall level, claiming that this is done to allow consumers devices to use the resources provided by this driver. But dependencies are in DT so manual ordering of init calls is not necessary any more. Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> --- Changes in the resend: - Change commit message to make clear that dependencies are in DT instead giving the impression that it was wishful thinking (Krzysztof Kozlowski). Hello, This patch was first sent as a part of a bigger series to allow the max77686 MFD driver to be built as a module [0]. The other patches were already picked but $SUBJECT wasn't, probably because there was a dependency with a patch on the exynos thermal driver [1]. But the exynos thermal patches also landed in mainline so I think it should be safe to merged $SUBJECT now.
