USB: spcp8x5: fix device initialisation at open

2013-06-20T19:01:38+00:00

commit 5e4211f1c47560c36a8b3d4544dfd866dcf7ccd0 upstream.

Do not use uninitialised termios data to determine when to configure the
device at open.

USB: f81232: fix device initialisation at open

2013-06-20T19:01:38+00:00

commit 21886725d58e92188159731c7c1aac803dd6b9dc upstream.

Do not use uninitialised termios data to determine when to configure the
device at open.

This also prevents stack data from leaking to userspace.

USB: pl2303: fix device initialisation at open

2013-06-20T19:01:38+00:00

commit 2d8f4447b58bba5f8cb895c07690434c02307eaf upstream.

Do not use uninitialised termios data to determine when to configure the
device at open.

This also prevents stack data from leaking to userspace in the OOM error
path.

USB: io_ti: fix chars_in_buffer overhead

2013-06-13T17:49:49+00:00

commit b16634adce951a7371be931487034f7365971ed0 upstream.

Use the new generic usb-serial wait_until_sent implementation to wait
for hardware buffers to drain.

This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 263e1f9f ("USB:
io_ti: query hardware-buffer status in chars_in_buffer") without
breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak
and close).

USB: ftdi_sio: fix chars_in_buffer overhead

2013-06-13T17:49:49+00:00

commit a37025b5c702aaf87191cd75fcc42c54454f16f5 upstream.

Use the new generic usb-serial wait_until_sent implementation to wait
for hardware buffers to drain.

This removes the need to check the hardware buffers in chars_in_buffer
and thus removes the overhead introduced by commit 6f602912 ("usb:
serial: ftdi_sio: Add missing chars_in_buffer function") without
breaking tty_wait_until_sent (used by, for example, tcdrain, tcsendbreak
and close).

commit c4133648bbce9e6b425a74cc890c8e4df51acaa9 upstream.

Use usb-serial port rather than tty as argument to get_modem_status.

USB: serial: add generic wait_until_sent implementation

2013-06-13T17:49:48+00:00

commit dcf0105039660e951dfea348d317043d17988dfc upstream.

Add generic wait_until_sent implementation which polls for empty
hardware buffers using the new port-operation tx_empty.

The generic implementation will be used for all sub-drivers that
implement tx_empty but does not define wait_until_sent.

USB: mos7720: fix hardware flow control

2013-06-13T17:49:13+00:00

commit a26f009a070e840fadacb91013b2391ba7ab6cc2 upstream.

The register access to enable hardware flow control depends on the
device port number and not the port minor number.

commit 849513a7809175420d353625b6f651d961e99d49 upstream.

The control and bulk-message timeouts are specified in milliseconds and
should not depend on HZ.
