Subject: [PATCH 0/5] staging: vchiq: stop using compat_alloc_user_space

This driver is one of only a few remaining files using
compat_alloc_user_space() and copy_in_user() to implement the compat_ioctl
handlers.

Change it to be more like the other drivers, calling the underlying
implementation directly, which is generally simpler and less
error-prone.

This is only build tested so far.
