609f9e92b5 spidev: BKL pushdown 
Add the BKL to spidev_open(), even though the existing locking looks
adequate.

d21c95c569 Add "no BKL needed" comments to several drivers 
This documents the fact that somebody looked at the relevant open()
functions and concluded that, due to their trivial nature, no locking was
needed.

20613f24bc usbcore: cdev lock_kernel() pushdown 
usb_open() is protected by a down_read(&minor_rwsem), but I'm not sure I
trust it to protect everything including subsidiary open() functions.

52de114e35 m68k: Prefix ISA type with ISA_TYPE_

(e.g. with `AMIGAHW_DECLARE(GG2_ISA)' in <asm/amigahw.h>) for some kernel
configurations. Use ISA_TYPE_* to avoid such conflicts.
