Currently debugfs entries for a DAPM widgets are only added in
snd_soc_dapm_debugfs_init. If a widget is added later (for example in the
dai_link's probe callback) it will not show up in debugfs.
This patch moves the creation of the widget debugfs entry to
snd_soc_dapm_new_widgets where it will be added after the widget has been
properly instantiated.
As a side-effect this will also reduce the number of times the DAPM widget list
is iterated during a card's instantiation.
Since it is possible that snd_soc_dapm_new_widgets is invoked form the codecs or
cards probe callbacks, the creation of the debugfs dapm directory has to be
moved before these are called.

The current code is clearing in_lpm flag after enabling the IRQ.
If IRQ comes immediately before in_lpm flag is set, it thinks that
hardware is in low power mode and disables the IRQ. Fix this by
clearing in_lpm flag before enabling the IRQ.

Some of the simulators may cache the ep0 maxpacket size to zero
if the ep0 dQh is not setup before enabling the pullup. Hence
Setup ep0 and initialize the dQh fields once while registering the
gadget(before enabling the pullup).
HSUSB Chipidea link controller spec says ep0 is enabled always
in the HW. Hence disabling and enabling the ep0 as a part of
reset interrupt is unneccesary.
Remove the disable/enable ep0 logic from reset interrupt handling.

As pointed out by Arnd Bergmann, in include/linux/usb/ehci_def.h, struct
ehci_caps is defined with __attribute__((packed)) for no good reason,
and this triggers undefined behaviour when using ARM's readl() on
pointers to elements of this structure:
http://lkml.kernel.org/r/201102021700.20683.arnd@arndb.de
The same problem exists with the other two structures in ehci_def.h too,
so remove the __attribute__((packed)) from all of them.

ext4_symlink() cannot call __page_symlink() with transaction open.
__page_symlink() calls ext4_write_begin() which can wait for
transaction commit if we are running out of space thus causing a
deadlock. Also error recovery in ext4_truncate_failed_write() does not
count with the transaction being already started (although I'm not
aware of any particular deadlock here).
Fix the problem by stopping a transaction before calling
__page_symlink() (we have to be careful and put inode to orphan list
so that it gets deleted in case of crash) and starting another one
after __page_symlink() returns for addition of symlink into a
directory.

When make_indexed_dir() fails (e.g. because of ENOSPC) after it has
allocated block for index tree root, we did not properly mark all
changed buffers dirty. This lead to only some of these buffers being
written out and thus effectively corrupting the directory.
Fix the issue by marking all changed data dirty even in the error
failure case.

Added a new driver for supporting Digigram Lola PCI-e boards.
Lola has a similar h/w design like HD-audio but with extended verbs.
Thus the driver is written similarly like HD-audio driver in the bus
part. The codec part is rather written in a fixed way specific to the
Lola board because of the verb incompatibility.
The driver provides basic PCM, supporting multi-streams and mixing.
