commit 528a572dae ("ide: add ->chipset field
to ide_pci_device_t") broke hwif->chipset setup (it is now set to ide_cmd646
for CMD648 instead of CMD646). It seems that the breakage happend while
I was moving patches around (cmd64x_chipsets[] entries for CMD646 and CMD648
are identical except for 'name' field). Fix it and bump driver version.

Use ide_cd_release() to do the cleanup if ide_cdrom_setup() fails.
It fixes:
- the default drive->dsc_overlap value not being restored
- the default drive->queue's prep_rq_fn not being restored
- struct gendisk 'g' not being freed
- wrong function name being reported on unregister_cdrom() error

cdi->mask is cleared by ide_cdrom_register() which is called after the quirk.
Fix it by adding new ->no_speed_select flag to struct ide_cd_config_flags
and using it in ide_cdrom_register() to set CDC_SELECT_SPEED flag.

USB: New device ID for the CP2101 driver
USB: VID/PID update for sierra
USB: Unbreak fsl_usb2_udc
Commit 5a52bd4a2d introduced a subtle logic
change in tty_wait_until_sent(). The original version would only error out
of the 'do { ... } while (timeout)' loop if signal_pending() evaluated to
true; a timeout or break due to an empty buffer would fall out of the loop
and into the tty->driver->wait_until_sent handling. The current
implementation will error out on either a pending signal or an empty
buffer, falling through to the tty->driver->wait_until_sent handling only
on a timeout.
The ->wait_until_sent() will not be reached if the buffer empties before
timeout jiffies have elapsed. This behavior differs from that prior to commit
5a52bd4a2d.
I turned this up while using a little serial download utility to bootstrap an
ARM-based eval board. The util worked fine on 2.6.22.x, but consistently
failed on 2.6.23.x. Once I'd determined that, I narrowed things down with git
bisect, and found the above difference in logic in tty_wait_until_sent() by
inspection.
This change reverts the logic flow in tty_wait_until_sent() to match that
prior to the aforementioned commit.

Zhe Jiang noticed that its possible to underflow pl->events in
prop_norm_percpu() when the value returned by percpu_counter_read() is less
than the error on that read and the period delay > 1. In that case half might
not trigger the batch increment and the value will be identical on the next
iteration, causing the same half to be subtracted again and again.
Fix this by rewriting the division as a single subtraction instead of a
subtraction loop and using percpu_counter_sum() when the value returned by
percpu_counter_read() is smaller than the error.
The latter is still needed if we want pl->events to shrink properly in the
error region.

Due to the change in kobject name handling, the module kobject needs to
have a null release function to ensure that the name it previously set
will be properly cleaned up.
All of this wierdness goes away in 2.6.25 with the rework of the kobject
name and cleanup logic, but this is required for 2.6.24.

Both store MAC address in CIS; there's no decoder for that
type (0x88) so the drivers work with raw data. It is
byteswapped, so ntohs() works for little-endian, but for
big-endian it's wrong. ntohs(le16_to_cpu()) does the
right thing on both (and always expands to swab16()).
