One exception is the s390 architecture, where a compat pointer is only 31 bit wide, and converting it into a 64-bit pointer requires calling compat_ptr(). Most drivers here will never run in s390, but since we now have a generic helper for it, it's easy enough to use it consistently. I double-checked all these drivers to ensure that all ioctl arguments are used as pointers or are ignored, but are not interpreted as integer values.

In practice this does not matter, since none of them are used on the s390 architecture and for all other architectures, compat_ptr() does not do anything, but using the new compat_ptr_ioctl() helper makes it more correct in theory, and simplifies the code. I checked that all ioctl handlers in these files are compatible and take either pointer arguments or no argument.
