Merge tag 'imx-fixes-4.16' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes
Pull "i.MX fixes for 4.16" from Shawn Guo:
- Fix i.MX GPC driver to remove power domains only when they are
initialized in imx_gpc_probe().
- Fix the broken Engicam i.CoreM6 DualLite/Solo RQS board DT to include
imx6dl.dtsi instead of imx6q.dtsi.
* tag 'imx-fixes-4.16' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
ARM: dts: imx6dl: Include correct dtsi file for Engicam i.CoreM6 DualLite/Solo RQS
soc: imx: gpc: de-register power domains only if initialized
