After having the mfd-driver for the PCF50633 in upstream, we need to remove the old driver from drivers/i2c/chips because it may break the kernel build if CONFIG_SENSORS_PCF50633 and CONFIG_MFD_PCF50633 are defined simultaniously.
After applying the following two patches the file drivers/i2c/chips/pcf50633.c can be removed. Best regards, Sven
