Suspend scenario in case of ohci-spear glue was not
properly handled as it was not suspending generic part
of ohci controller. Alan Stern suggested, properly handle
ohci-spear suspend scenario.
Calling explicitly the ohci_suspend() routine in
spear_ohci_hcd_drv_suspend() will ensure proper
handling of suspend scenario.

The commit "usb: usbtest: support bos descriptor test for usb 3.0"
introduced a test for bos descriptor. And USB 2.1 device also can be
checked. So this patch extends the test coverage to support USB 2.1 device.

USB 2.1 Link PM adds to use bits[1:15] according to USB 2.0 ECN Errata for
Link Power Management spec.
Bit Encoding
0 Reserved
1 LPM
2 BESL & Altemate HIRD definitions supported
3 Recommended Baseline BESL valid
4 Recommended Deep BESL valid
11:8 Recommended Baseline BESL value
15:12 Recommended Deep BESL value
31:16 Reserved
So fix the bit mask from 0x1e to 0xfffe.

Replace the .find_device function pointer in struct acpi_bus_type
with a new one, .find_companion, that is supposed to point to a
function returning struct acpi_device pointer (instead of an int)
and takes one argument (instead of two). This way the role of
this callback is more clear and the implementation of it can
be more straightforward.
Update all of the users of struct acpi_bus_type (PCI, PNP/ACPI and
USB) to reflect the structure change.

Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.
First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.
Second, there are ordering dependencies between those files that always
have to be met. Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there. And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds. That also is taken care of including
<linux/acpi.h> as appropriate.

/c/kernel-tests/src/cocci/drivers/usb/host/ehci-mv.c:181:26-27: WARNING comparing pointer to 0
Compare pointer-typed values to NULL rather than 0
Semantic patch information:
This makes an effort to choose between !x and x == NULL. !x is used
if it has previously been used with the function used to initialize x.
This relies on type information. More type information can be obtained
using the option -all_includes and the option -I to specify an
include path.

Compliance Mode in hub_events() when trying to decide which reset
function to use. Trying to call usb_reset_device() with a NOTATTACHED
