Some of the register names defined here are matching with registers defined in other places. Like DCR is defined here and DCR is also a register in mn10300 architecture.

2015-04-29USB: visor: Match I330 phone more preciselyJason A. Donenfeld
Samsung has just released a portable USB3 SSD, coming in a very small and nice form factor. It's USB ID is 04e8:8001, which unfortunately is already used by the Palm Visor driver for the Samsung I330 phone cradle. Having pl2303 or visor pick up this device ID results in conflicts with the usb-storage driver, which handles the newly released portable USB3 SSD. To work around this conflict, I've dug up a mailing list post [1] from a long time ago, in which a user posts the full USB descriptor information. The most specific value in this appears to be the interface class, which has value 255 (0xff). Since usb-storage requires an interface class of 0x8, I believe it's correct to disambiguate the two devices by matching on 0xff inside visor.

2015-03-02USB: ch341: set tty baud speed according to tty structNicolas PLANEL
The ch341_set_baudrate() function initialize the device baud speed according to the value on priv->baud_rate. By default the ch341_open() set it to a hardcoded value (DEFAULT_BAUD_RATE 9600). Unfortunately, the tty_struct is not initialized with the same default value. (usually 56700) This means that the tty_struct and the device baud rate generator are not synchronized after opening the port. Fixup is done by calling ch341_set_termios() if tty exist. Remove unnecessary variable priv->baud_rate setup as it's already done by ch341_port_probe(). Remove unnecessary call to ch341_set_{handshake,baudrate}() in ch341_open() as there already called in ch341_configure() and ch341_set_termios() Signed-off-by: Nicolas PLANEL <nicolas.planel@enovance.com> Signed-off-by: Johan Hovold <johan@kernel.org>
