Aborting a SCSI cmnd might requrie to send a abort_fsf_cmnd. If the
creation of this fsf_req fails an ERR_PTR is returned where a NULL
value would be expected as an error indicator. This ERR_PTR is
dereferenced as valid fsf_req in succeeding processing leading to
an error.

When the "hpwdt" module is loaded (even if the /dev/watchdog device is not
opened), then kdump does not work. The panic kernel either does not start at
all or crash in various places.
The problem is that hpwdt_pretimeout is registered with register_die_notifier()
with the highest possible priority. Because it returns NOTIFY_STOP, the
crash_nmi_callback which is also registered with register_die_notifier()
is never executed. This causes the shutdown of other CPUs to fail.
Reverting the order is no option: The crash_nmi_callback executes HLT
and so never returns normally. Because of that, it must be executed as
last notifier, which currently is done.
So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

ml_ff_playback() uses spin_(un)lock_bh. However this function is called
with interrupts disabled from erase_effect() in drivers/input/ff-core.c:196.
This is not permitted, and will result in a WARN_ON in the bottom half handling code.
This patch changes this function to just use spin_lock_irqsave() instead, solving
the problem and simplifying the locking logic.

c) hisax_register() is passing to checkcard() full-blown hisax_cs_setup_card():
checkcard(i, id, NULL, hisax_d_if->owner, hisax_cs_setup_card);
The problem with it is that
* hisax_cs_setup_card() is __devinit
* hisax_register() is not
* hisax_cs_setup_card() is a switch from hell, calling a lot of
setup_some_weirdcard() depending on card->typ. _These_ are also
__devinit.
However, in hisax_register() we have card->typ equal to
ISDN_CTYPE_DYNAMIC, which reduces hisax_cs_setup_card() to "nevermind
all that crap, just do nothing and return 2". So we add a
trimmed-down callback doing just that and passed to checkcard() by
hisax_register(). _This_ is non-init (we can stand the impact on
.text size).

The code
if (shost->dma_channel != NO_ISA_DMA)
free_dma(shost->dma_channel);
in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to
something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is
not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into
undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false
positive.
Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and
dependency on free_dma() disappears for !CONFIG_ISA.

The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.
All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.
To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.
The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.
CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.
