The MFD_VEXPRESS_SYSREG driver selects CLKSRC_MMIO, which in turn conflicts with ARCH_USES_GETTIMEOFFSET, causing a harmless Kconfig warning when it is set: warning: (ARCH_MVEBU && ARCH_DIGICOLOR && ARCH_GEMINI && ARCH_KEYSTONE && ARCH_MOXART && ARCH_MXS && PLAT_SPEAR && ARCH_SUNXI && ARCH_TEGRA && ARCH_U300 && PLAT_ORION && ARCH_CLPS711X && ARCH_EP93XX && ARCH_NETX && ARCH_IXP4XX && ARCH_KS8695 && ARCH_W90X900 && ARCH_PXA && ARCH_SA1100 && ARCH_OMAP1 && ARCH_BCM_IPROC && ARCH_INTEGRATOR_AP && ARCH_OMAP2PLUS && MFD_VEXPRESS_SYSREG) selects CLKSRC_MMIO which has unmet direct dependencies (!ARCH_USES_GETTIMEOFFSET) This was apparently hidden by the fact that no ARM platform that still sets ARCH_USES_GETTIMEOFFSET has gpiolib support, and we already have a dependency on GPIOLIB that I added a while ago. However, after 296ad4ac ("gpio: remove deps on ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"), any platform can enable CONFIG_GPIOLIB, and that lets us enable MFD_VEXPRESS_SYSREG as well. This adds an explicit dependency on !ARCH_USES_GETTIMEOFFSET to guarantee that we can enable the CLKSRC_MMIO driver without getting warnings. Signed-off-by:

SMSC MFD driver does not add any MFD child devices via mfd_add_devices() and hence it is not required to call mfd_remove_devices() to remove MFD child devices. Remove the call of the API mfd_remove_devices() which will result as remove of .remove callback for driver. Signed-off-by:

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:
