+Subject: [PATCH] v4l2object: fix type mismatch when ioctl takes int
+
+v4l2object->ioctl can either be set to v4l2_ioctl() or ioctl().
+v4l2_ioctl() always takes the request number as unsigned long int, but ioctl()
+may take (at least) unsigned long int, int, or unsigned, depending on libc.
+This means that there isn't one function pointer type that can be used for
+v4l2object->ioctl that will always be able to accomodate being set to either of
+v4l2_ioctl() and ioctl().  It's therefore necessary to wrap one of them so that
+both options can have the same type.  This fixes an assignment from incompatible
+pointer type error when building for musl.
