This is a note to let you know that I've just added the patch titled
ARM: amba: Make driver_override output consistent with other buses
to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices.
Make AMBA consistent with other buses by dropping the test for a NULL pointer.
Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)".
