This reverts commit 90593899.

SAM-BA devices identify themselves CDC-ACM devices and should be using
the cdc-acm driver.

Since commit 5b239f0a (USB: cdc-acm: Add pseudo
modem without AT command capabilities) cdc-acm also binds to them.

Note that the Atmel SAM-BA tools expect to use a USB-serial driver and thus
require a symlink from /dev/ttyACMn to some /dev/ttyUSBm (with m < 30) to be
able to select the device. This is simply a UI-issue that should be
fixed by Atmel.

Tested with the SAM-BA 2.10 tools and an Atmel at91sam9260-ek.

The twl4030-usb driver exports the status of VBUS as sysfs attribute.
In case an accessory charger adapter (ACA) is connected to the OTG
transceiver the attribute is always 'off', even when the charger
provides VBUS. Added a variable to keep track of the status of VBUS
and report it correctly

This patch (as1457) abandons the curious strategy of declaring a
controller dead following hibernation merely in order to reset and
then revive it.  The core no longer allow dead controllers to spring
back to life when the system resumes, so there's no reason to declare
a working controller temporarily dead.  Instead we do an explicit
reset.

This patch (as1456) removes all uses of hcd->state from the uhci-hcd
driver, as part of the overall strategy to eliminate hcd->state
completely.  Now when a controller dies we call usb_hc_died()
directly, instead of relying on the core interrupt handler to see that
hcd->state has changed to HC_STATE_HALT and make the call for us.

Fix 41 occurrences of this type of Section mismatch warning
in g_mass_storage, g_serial, g_cdc, g_multi, g_nokia, g_ether, g_ffs:
(the 75 number reported earlier contained some duplicates.)

WARNING: drivers/usb/gadget/g_mass_storage.o(.text+0x687a): Section mismatch in reference from the function fsg_bind() to the function .devinit.text:usb_ep_autoconfig()
The function fsg_bind() references
the function __devinit usb_ep_autoconfig().
This is often because fsg_bind lacks a __devinit
annotation or the annotation of usb_ep_autoconfig is wrong.

Also remove __devinit from usb_ep_autoconfig_reset() to prevent
possible section mismatch problems with it.

This patch (as1455) removes the extra padding sent by g_file_storage
and g_mass_storage when the gadget wants to send less data than
requested by the host and isn't allowed to halt the bulk-IN endpoint.

Although the Bulk-Only Transport specification requires the padding to
be present, it isn't truly needed since the transfer will be terminated
by a short packet anyway.  Furthermore, many existing devices don't
bother to send any padding.

Mass-storage and file-storage gadgets align the length to maximum-packet-size
when preparing the request to receive CBW. This is unnecessary and prevents the
controller driver from knowing that a short-packet is expected.

It is incorrect to set short_not_ok when preparing the request to receive CBW.
CBW will be a short-packet so short_not_ok must not be set.

This makes bh->bulk_out_intended_length unnecessary so it is also removed.
