I dropped this patch since the zoran driver will be removed for 5.2,
so there is no point in applying this patch.

Also, for future reference, please provide the name of the driver that
you are patching in the subject. I.e. something like this:

[PATCH] zoran: fixed coding style: do not initialise statics to NULL

That helps triage for maintainers.
