Hit this problem while testing RAID1 failure stuff. open_bdev_exclusive returns ERR_PTR(), not NULL. So change the return value properly. This is important if you accidently specify a device that doesn't exist when trying to add a new device to an array, you will panic the box dereferencing bdev.

I have written a small patch that let's me use my Amiga CD32
joypad connected to the parallel port. Thought I'd share it with you so
you can add it to the list of supported joysticks (hopefully someone will
find it useful).
It needs the following wiring:
CD32 pad | Parallel port
----------------------------
1 (Up) | 2 (D0)
2 (Down) | 3 (D1)
3 (Left) | 4 (D2)
4 (Right) | 5 (D3)
5 (Fire3) | 14 (AUTOFD)
6 (Fire1) | 17 (SELIN)
7 (+5V) | 1 (STROBE)
8 (Gnd) | 18 (Gnd)
9 (Fire2) | 7 (D5)
