USB: spcp8x5: correct handling of CS5 setting

2013-12-12T06:36:28+00:00

commit 711fbdfbf2bc4827214a650afe3f64767a1aba16 upstream.

This patch removes an erroneous check of CSIZE, which made it impossible to set
CS5.

Compiles clean, but couldn't test against hardware.

USB: ftdi_sio: fixed handling of unsupported CSIZE setting

2013-12-12T06:36:28+00:00

commit 8704211f65a2106ba01b6ac9727cdaf9ca11594c upstream.

FTDI UARTs support only 7 or 8 data bits. Until now the ftdi_sio driver would
only report this limitation for CS6 to dmesg and fail to reflect this fact to
tcgetattr.

This patch reverts the unsupported CSIZE setting and reports the fact with less
severance to dmesg for both CS5 and CS6.

To test the patch it's sufficient to call

    stty -F /dev/ttyUSB0 cs5

which will succeed without the patch and report an error with the patch
applied.

As an additional fix this patch ensures that the control request will always
include a data bit size.

USB: pl2303: fixed handling of CS5 setting

2013-12-12T06:36:28+00:00

commit a313249937820f8b1996133fc285efbd6aad2c5b upstream.

This patch fixes the CS5 setting on the PL2303 USB-to-serial devices. CS5 has a
value of 0 and the CSIZE setting has been skipped altogether by the enclosing
if. Tested on 3.11.6 and the scope shows the correct output after the fix has
been applied.

Tagged to be added to stable, because it fixes a user visible driver bug and is
simple enough to backport easily.

usb: hub: Clear Port Reset Change during init/resume

2013-11-29T19:11:52+00:00

commit e92aee330837e4911553761490a8fb843f2053a6 upstream.

This patch adds the Port Reset Change flag to the set of bits that are
preemptively cleared on init/resume of a hub. In theory this bit should
never be set unexpectedly... in practice it can still happen if BIOS,
SMM or ACPI code plays around with USB devices without cleaning up
correctly. This is especially dangerous for XHCI root hubs, which don't
generate any more Port Status Change Events until all change bits are
cleared, so this is a good precaution to have (similar to how it's
already done for the Warm Port Reset Change flag).

usb: fail on usb_hub_create_port_device() errors

2013-11-20T20:27:47+00:00

commit e58547eb9561a8a72d46e2d411090a614d33ac0e upstream.

Ignoring usb_hub_create_port_device() errors cause later NULL pointer
deference when uninitialized hub->ports[i] entries are dereferenced
after port memory allocation error.

usb: fix cleanup after failure in hub_configure()

2013-11-20T20:27:47+00:00

commit d0308d4b6b02597f39fc31a9bddf7bb3faad5622 upstream.

If the hub_configure() fails after setting the hdev->maxchild
the hub->ports might be NULL or point to uninitialized kzallocated
memory causing NULL pointer dereference in hub_quiesce() during cleanup.

Now after such error the hdev->maxchild is set to 0 to avoid cleanup
of uninitialized ports.
