Subject: Re: [PATCH v2 03/17] compat_ioctl: use correct compat_ptr() translation in drivers

Arnd Bergmann <arnd@arndb•de> writes:
> A handful of drivers all have a trivial wrapper around their ioctl

> does not do anything, but using the new generic_compat_ioctl_ptrarg
> helper makes it more correct in theory, and simplifies the code.
