2006-03-25[PATCH] hp300: fix driver_register() return handling, remove dio_module_init()Bjorn Helgaas
Remove the assumption that driver_register() returns the number of devices bound to the driver. In fact, it returns zero for success or a negative error value. dio_module_init() used the device count to automatically unregister and unload drivers that found no devices. That might have worked at one time, but has been broken for some time because dio_register_driver() returned either a negative error or a positive count (never zero). So it could only unregister on failure, when it's not needed anyway. This functionality could be resurrected in individual drivers by counting devices in their .probe() methods.

2006-03-20[SERIAL] kernel console should send CRLF not LFCRRussell King
Glen Turner reported that writing LFCR rather than the more traditional CRLF causes issues with some terminals.

2006-03-20[SPARC] serial: Make sure sysfs nodes get named correctly.David S. Miller
Because we play this trick where we use ttyS? in increasing minor numbers for different sunfoo.c drivers, we have to inform the TTY layer of this. Do so by setting the tty->name_base appropriately. Probably there should be a generic way to do this in the serial core, but for now... Signed-off-by: David S. Miller <davem@davemloft.net>
2006-03-20[SPARC64] sunhv: Fix locking in sunhv_start_tx()David S. Miller

2006-03-08[PATCH] serial core: work around sub-driver bugsPavel Machek
We're presently getting oopses because Bluetooth (and possibly other) drivers are calling core functions after things have been shut down.
