usb: gadget: u_serial: add missing port entry locking

2019-12-13T07:42:20Z

commit daf82bd24e308c5a83758047aff1bd81edda4f11 upstream. gserial_alloc_line() misses locking (for a release barrier) while resetting port entry on TTY allocation failure. Fix this.

USB: serial: ftdi_sio: add device IDs for U-Blox C099-F9P

2019-12-04T21:30:48Z

commit c1a1f273d0825774c80896b8deb1c9ea1d0b91e3 upstream. This device presents itself as a USB hub with three attached devices: - An ACM serial port connected to the GPS module (not affected by this commit) - An FTDI serial port connected to the GPS module (1546:0502) - Another FTDI serial port connected to the ODIN-W2 radio module (1546:0503) This commit registers U-Blox's VID and the PIDs of the second and third devices.

usb: dwc2: use a longer core rest timeout in dwc2_core_reset()

2019-12-04T21:30:45Z

commit 6689f0f4bb14e50917ba42eb9b41c25e0184970c upstream. Testing on different generations of Lantiq MIPS SoC based boards, showed that it takes up to 1500 us until the core reset bit is cleared. The driver from the vendor SDK (ifxhcd) uses a 1 second timeout. Use the same timeout to fix wrong hang detections and make the driver work for Lantiq MIPS SoCs. At least till kernel 4.14 the hanging reset only caused a warning but the driver was probed successful. With kernel 4.19 errors out with EBUSY.

commit f0797095423e6ea3b4be61134ee353c7f504d440 upstream. These are the Foxconn-branded variants of the Dell DW5821e modules, same USB layout as those.

USB: serial: mos7840: fix remote wakeup

2019-11-29T09:10:27Z

commit 92fe35fb9c70a00d8fbbf5bd6172c921dd9c7815 upstream. The driver was setting the device remote-wakeup feature during probe in violation of the USB specification (which says it should only be set just prior to suspending the device). This could potentially waste power during suspend as well as lead to spurious wakeups. Note that USB core would clear the remote-wakeup feature at first resume.
