ath9k_htc: Fix disconnect issue in HT40 mode.

commit 71ba186c123630ddab17667ec9ecf7e2ef211295 upstream.

Some APs advertise that they may be HT40 capable in the capabilites
but the current operating channel configuration may be only HT20.
This causes disconnection as ath9k_htc sets WLAN_RC_40_FLAG despite
the AP operating in HT20 mode.
Hence set this flag only if the current channel configuration
is HT40 enabled.

ath9k_hw: Fix EEPROM uncompress block reading on AR9003

commit 803288e61e346ba367373bc7d5eeb6e11c81a33c upstream.

The EEPROM is compressed on AR9003, upon decompression
the wrong upper limit was being used for the block which
prevented the 5 GHz CTL indexes from being used, which are
stored towards the end of the EEPROM block. This fix allows
the actual intended regulatory limits to be used on AR9003
hardware.

ath9k_hw: fix parsing of HT40 5 GHz CTLs

commit 904879748d7439a6dabdc6be9aad983e216b027d upstream.

The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.

ocfs2: Fix incorrect checksum validation error

commit f5ce5a08a40f2086435858ddc80cb40394b082eb upstream.

For local mounts, ocfs2_read_locked_inode() calls ocfs2_read_blocks_sync() to
read the inode off the disk. The latter first checks to see if that block is
cached in the journal, and, if so, returns that block. That is ok.

But ocfs2_read_locked_inode() goes wrong when it tries to validate the checksum
of such blocks. Blocks that are cached in the journal may not have had their
checksum computed as yet. We should not validate the checksums of such blocks.

USB: ehci-ppc-of: problems in unwind

commit 08a3b3b1c2e622e378d9086aee9e2e42ce37591d upstream.

The iounmap(ehci->ohci_hcctrl_reg); should be the first thing we do
because the ioremap() was the last thing we did.  Also if we hit any of
the goto statements in the original code then it would have led to a
NULL dereference of "ehci".  This bug was introduced in: 796bcae7361c

usb: allow drivers to use allocated bandwidth until unbound

commit 0791971ba8fbc44e4f476079f856335ed45e6324 upstream.

When using the remove sysfs file, the device configuration is set to -1
(unconfigured). This eventually unbind drivers with the bandwidth_mutex
held. Some drivers may call functions that hold said mutex, like
usb_reset_device. This is the case for rtl8187, for example. This will
lead to the same process holding the mutex twice, which deadlocks.

Besides, according to Alan Stern:
"The deadlock problem probably could be handled somehow, but there's a
separate issue: Until the usb_disable_device call finishes unbinding
the drivers, the drivers are free to continue using their allocated
bandwidth.  We musn't change the bandwidth allocations until after the
unbinding is done.  So this patch is indeed necessary."

Unbinding the driver before holding the bandwidth_mutex solves the
problem. If any operation after that fails, drivers are not bound again.
But that would be a problem anyway that the user may solve resetting the
device configuration to one that works, just like he would need to do in
most other failure cases.

ima: always maintain counters

commit e950598d43dce8d97e7d5270808393425d1e5cbd upstream.

commit 8262bb85da allocated the inode integrity struct (iint) before any
inodes were created. Only after IMA was initialized in late_initcall were
the counters updated. This patch updates the counters, whether or not IMA
has been initialized, to resolve 'imbalance' messages.

This patch fixes the bug as reported in bugzilla: 15673.  When the i915
is builtin, the ring_buffer is initialized before IMA, causing the
imbalance message on suspend.

USB: cxacru: Use a bulk/int URB to access the command endpoint

commit 902ffc3c707c1d459ea57428a619a807cbe412f9 upstream.

The command endpoint is either a bulk or interrupt endpoint, but using
the wrong type of transfer causes an error if CONFIG_USB_DEBUG is
enabled after commit f661c6f8c67bd55e93348f160d590ff9edf08904, which
checks for this mismatch.

Detect which type of endpoint it is and use a bulk/int URB as
appropriate. There are other function calls specifying a bulk pipe,
but usb_clear_halt doesn't use the pipe type (only the endpoint) and
usb_bulk_msg auto-detects interrupt transfers.

USB: cdc-acm: Adding second ACM channel support for various Nokia and one Samsung phones

commit 4035e45632c2a8bb4edae83c20447051bd9a9604 upstream.

S60 phones from Nokia and Samsung expose two ACM channels. The first is a modem
with a standard AT-command interface, which is picked up correctly by CDC-ACM.

The second ACM port is marked as having a vendor-specific protocol. This means
that the ACM driver will not claim the second channel by default.

This adds support for the second ACM channel for the following devices:
    Nokia E63
    Nokia E75
    Nokia 6760 Slide
    Nokia E52
    Nokia E55
    Nokia E72
    Nokia X6

USB: cdc-acm: Fixing crash when ACM probing interfaces with no endpoint descriptors.

commit 577045c0a76e34294f902a7d5d60e90b04d094d0 upstream.

Certain USB devices, such as the Nokia X6 mobile phone, don't expose any
endpoint descriptors on some of their interfaces. If the ACM driver is forced
to probe all interfaces on a device the a NULL pointer dereference will occur
when the ACM driver attempts to use the endpoint of the alternative settings.
One way to get the ACM driver to probe all the interfaces is by using the
/sys/bus/usb/drivers/cdc_acm/new_id interface.

This patch checks that the endpoint pointer for the current alternate settings
is non-NULL before using it.

ALSA: usb-audio: fix detection of vendor-specific device protocol settings

commit a2acad8298a42b7be684a32fafaf83332bba9c2b upstream.

The Audio Class v2 support code in 2.6.35 added checks for the
bInterfaceProtocol field.  However, there are devices (usually those
detected by vendor-specific quirks) that do not have one of the
predefined values in this field, which made the driver reject them.

To fix this regression, restore the old behaviour, i.e., assume that
a device with an unknown bInterfaceProtocol field (other than
UAC_VERSION_2) has more or less UAC-v1-compatible descriptors.
