Subject: Input: uinput - handle compat ioctl for UI_SET_PHYS

From: Ricky Liang <[email protected]>

commit affa80bd97f7ca282d1faa91667b3ee9e4c590e6 upstream.

When running a 32-bit userspace on a 64-bit kernel, the UI_SET_PHYS ioctl needs to be treated with special care, as it has the pointer size encoded in the command.
