net, compat_ioctl: handle socket ioctl abuses in tty drivers
Slip and a few other drivers use the same ioctl numbers on tty devices that are normally meant for sockets. This causes problems with our compat_ioctl handling that tries to convert the data structures in a different format. Fortunately, these five drivers all use 32 bit compatible data structures in the ioctl numbers, so we can just add a trivial compat_ioctl conversion function to each of them. SIOCSIFENCAP and SIOCGIFENCAP do not need to live in fs/compat_ioctl.c after this any more, and they are not used on any sockets. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
