I have merged this one and 8/8 into: https://git.kernel.org/pub/scm/linux/kernel/git/hansg/linux.git/log/?h=media-atomisp I'm currently doing a lot of work on the atomisp code, so merging them through my atomisp branch is best to avoid conflicts (I already had to resolve a conflict). So please refrain from merging 1/8 + 8/8 to some other linux-media tree/branch.

I've delegated patches 1 and 8 to you in patchwork.

Fix a compiler warning: drivers/staging/media/atomisp/pci/atomisp_gmin_platform.c:1525:13: warning: 'settings' may be used uninitialized [-Wmaybe-uninitialized] The 'settings' variable is actually always initialized, but the compiler isn't quite able to figure that out. Just initialize it to 0 to avoid this warning.
