Benjamin Tissoires 5b1c071d5e HID: hidraw: tighten ioctl command parsing
[ Upstream commit 75d5546f60 ]

The handling for variable-length ioctl commands in hidraw_ioctl() is
rather complex and the check for the data direction is incomplete.

Simplify this code by factoring out the various ioctls grouped by dir
and size, and using a switch() statement with the size masked out, to
ensure the rest of the command is correctly matched.

Fixes: 9188e79ec3 ("HID: add phys and name ioctls to hidraw")
