Merge tag 'arm-soc/for-4.18/drivers' of https://github.com/Broadcom/stblinux into next/drivers
This pull request contains Broadcom ARM/ARM64/MIPS SoCs drivers changes for 4.18, please pull the following: - Florian removes the synthetic struct device in the DPFE driver which was used to attach sysfs attributes and uses the platform_device we are probed from instead. * tag 'arm-soc/for-4.18/drivers' of https://github.com/Broadcom/stblinux: memory: brcmstb: dpfe: Remove need for dpfe_dev Signed-off-by: Olof Johansson <olof@lixom.net>
