Bluetooth: Fix issue with USB suspend in btusb driver

2014-10-30T16:38:23+00:00

commit 85560c4a828ec9c8573840c9b66487b6ae584768 upstream.

Suspend could fail for some platforms because
btusb_suspend==> btusb_stop_traffic ==> usb_kill_anchored_urbs.

When btusb_bulk_complete returns before system suspend and resubmits
an URB, the system cannot enter suspend state.

Bluetooth: Fix HCI H5 corrupted ack value

2014-10-30T16:38:23+00:00

commit 4807b51895dce8aa650ebebc51fa4a795ed6b8b8 upstream.

In this expression: seq = (seq - 1) % 8
seq (u8) is implicitly converted to an int in the arithmetic operation.
So if seq value is 0, operation is ((0 - 1) % 8) => (-1 % 8) => -1.
The new seq value is 0xff which is an invalid ACK value, we expect 0x07.
It leads to frequent dropped ACK and retransmission.
Fix this by using '&' binary operator instead of '%'.

rt2800: correct BBP1_TX_POWER_CTRL mask

2014-10-30T16:38:23+00:00

commit 01f7feeaf4528bec83798316b3c811701bac5d3e upstream.

Two bits control TX power on BBP_R1 register. Correct the mask,
otherwise we clear additional bit on BBP_R1 register, what can have
unknown, possible negative effect.

PCI: Generate uppercase hex for modalias interface class

2014-10-30T16:38:23+00:00

commit 89ec3dcf17fd3fa009ecf8faaba36828dd6bc416 upstream.

Some implementations of modprobe fail to load the driver for a PCI device
automatically because the "interface" part of the modalias from the kernel
is lowercase, and the modalias from file2alias is uppercase.

The "interface" is the low-order byte of the Class Code, defined in PCI
r3.0, Appendix D.  Most interface types defined in the spec do not use
alpha characters, so they won't be affected.  For example, 00h, 01h, 10h,
20h, etc. are unaffected.

Print the "interface" byte of the Class Code in uppercase hex, as we
already do for the Vendor ID, Device ID, Class, etc.

PCI: Increase IBM ipr SAS Crocodile BARs to at least system page size

2014-10-30T16:38:23+00:00

commit 9fe373f9997b48fcd6222b95baf4a20c134b587a upstream.

The Crocodile chip occasionally comes up with 4k and 8k BAR sizes.  Due to
an erratum, setting the SR-IOV page size causes the physical function BARs
to expand to the system page size.  Since ppc64 uses 64k pages, when Linux
tries to assign the smaller resource sizes to the now 64k BARs the address
will be truncated and the BARs will overlap.

Force Linux to allocate the resource as a full page, which avoids the
overlap.

PCI: mvebu: Fix uninitialized variable in mvebu_get_tgt_attr()

2014-10-30T16:38:23+00:00

commit 56fab6e189441d714a2bfc8a64f3df9c0749dff7 upstream.

Geert Uytterhoeven reported a warning when building pci-mvebu:

  drivers/pci/host/pci-mvebu.c: In function 'mvebu_get_tgt_attr':
  drivers/pci/host/pci-mvebu.c:887:39: warning: 'rtype' may be used uninitialized in this function [-Wmaybe-uninitialized]
     if (slot == PCI_SLOT(devfn) && type == rtype) {
					 ^

And indeed, the code of mvebu_get_tgt_attr() may lead to the usage of rtype
when being uninitialized, even though it would only happen if we had
entries other than I/O space and 32 bits memory space.

This commit fixes that by simply skipping the current DT range being
considered, if it doesn't match the resource type we're looking for.

tty: omap-serial: fix division by zero

2014-10-30T16:38:22+00:00

commit dc3187564e61260f49eceb21a4e7eb5e4428e90a upstream.

If the chosen baud rate is large enough (e.g. 3.5 megabaud), the
calculated n values in serial_omap_is_baud_mode16() may become 0. This
causes a division by zero when calculating the difference between
calculated and desired baud rates. To prevent this, cap the n13 and n16
values on 1.

Division by zero in kernel.
