USB: cypress_m8: fix ring-indicator detection and reporting

2014-02-06T19:05:46Z

commit 440ebadeae9298d7de3d4d105342691841ec88d0 upstream. Fix ring-indicator (RI) status-bit definition, which was defined as CTS, effectively preventing RI-changes from being detected while reporting false RI status. This bug predates git.

USB: serial: fix race in generic write

2014-01-08T17:42:10Z

commit 6f6485463aada1ec6a0f3db6a03eb8e393d6bb55 upstream. Fix race in generic write implementation, which could lead to temporarily degraded throughput. The current generic write implementation introduced by commit 27c7acf22047 ("USB: serial: reimplement generic fifo-based writes") has always had this bug, although it's fairly hard to trigger and the consequences are not likely to be noticed. Specifically, a write() on one CPU while the completion handler is running on another could result in only one of the two write urbs being utilised to empty the remainder of the write fifo (unless there is a second write() that doesn't race during that time).

USB: serial: option: blacklist interface 1 for Huawei E173s-6

2013-12-20T15:34:20Z

commit 8f173e22abf2258ddfa73f46eadbb6a6c29f1631 upstream. Interface 1 on this device isn't for option to bind to otherwise an oops on usb_wwan with log flooding will happen when accessing the port: tty_release: ttyUSB1: read/write wait queue active! It doesn't seem to respond to QMI if it's added to qmi_wwan so don't add it there - it's likely used by the card reader. Signed-off-by: Gustavo Zacarias Signed-off-by: Greg Kroah-Hartman

USB: spcp8x5: correct handling of CS5 setting

2013-12-12T06:34:11Z

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. Signed-off-by: Colin Leitner Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

USB: pl2303: fixed handling of CS5 setting

2013-12-12T06:34:11Z

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.
