Implement dynamic minor allocation for DVB, to allow more than four
devices of the same type per adapter, based on drivers/usb/core/file.c.
Add a new config option, DVB_DYNAMIC_MINORS, to make use of this
feature, which defaults to no for backwards compatibility.

* hpt366: set IDE_HFLAG_SERIALIZE in ->host_flags if needed
in init_hwif_hpt366(). Remove HPT_SERIALIZE_IO while at it.
* Set IDE_HFLAG_SERIALIZE in ->host_flags if needed in
ide_init_port().
* Convert init_irq() to use IDE_HFLAG_SERIALIZE together with
hwif->host to find out ports which need to be serialized.
* Remove no longer needed save_match() and ide_hwif_t.serialized.
v2:
* Set host's ->host_flags field instead of port's copy.
This patch should fix the incorrect grouping of port(s) from
host(s) that need serialization with port(s) that happen to use
the same IRQ(s) but are from the host(s) that don't need it.

Now that (almost) all host drivers have been fixed not to abuse ide_lock
and core code usage of ide_lock has been sanitized we may safely replace
ide_lock by per-hwgroup locks.
This patch is partially based on earlier patch from Ravikiran G Thirumalai.
While at it:
- don't use deprecated HWIF() and HWGROUP() macros
- update locking documentation in ide.h
v2:
Add missing spin_lock_init(&hwgroup->lock). (Noticed by Elias Oltmanns)

Commit 4dde4492d8 ("ide: make drive->id

at least on some machines confuses ACPI and breaks suspend. Fix it.
Fixes kernel.org bug #12279:
http://bugzilla.kernel.org/show_bug.cgi?id=12279
[ Sorry about the bug (IDE ACPI is not used by default so it managed
to slip in). Still it is kind of surprising that the bug breaks
suspend as it shouldn't impact anything except IDE ACPI (it seems
that it uncovered either some ACPI/PM deficiency or a BIOS bug). ]

in the message. Remove the whole special case: The failed "open port"
