Hi,
v2: Remove incorrect use of USB_CTRL_SET_TIMEOUT (=5000);
usb_stor_control_msg() timeout argument is actually specified in jiffies.
Please put the patch version changes under the --- tear-line.
usb_stor_euscsi_init() enables multi-target mode for SCM eUSB SCSI bridge
devices. The control message it sends has wLength = 1 and the byte sent is
0x01. While that works, the SCM driver does it with wLength = 0. We may as
well match what the SCM driver does.
This includes the change from
[PATCH] storage: Fix timeout in usb_stor_euscsi_init() and
usb_stor_huawei_e220_init()
