when the USB host controller is the parent of the connector, usually type-B, sometimes don't need the graph, so we should check whether it's parent registers usb-role-switch or not firstly, and get it if exists. Suggested-by:

There are bugs on vhci with usb 3.0 storage device. In USB, each SG list entry buffer should be divisible by the bulk max packet size. But with native SG support, this problem doesn't matter because the SG buffer is treated as contiguous buffer. But without native SG support, USB storage driver breaks SG list into several URBs and the error occurs because of a buffer size of URB that cannot be divided by the bulk max packet size. The error situation is as follows. When USB Storage driver requests 31.5 KB data and has SG list which has 3584 bytes buffer followed by 7 4096 bytes buffer for some reason. USB Storage driver splits this SG list into several URBs because VHCI doesn't support SG and sends them separately. So the first URB buffer size is 3584 bytes. When receiving data from device, USB 3.0 device sends data packet of 1024 bytes size because the max packet size of BULK pipe is 1024 bytes. So device sends 4096 bytes. But the first URB buffer h...

Enable static DRD mode in Intel platforms which guarantees successful role switch all the time. This fixes issues like software role switch failure after cold boot and issue with role switch when USB 3.0 cable is used. But, do not enable static DRD mode for Cherrytrail devices which rely on firmware for role switch. Signed-off-by:

Xhci re-enables a slot on transaction error in set_address using xhci_disable_slot() + xhci_alloc_dev(). But in this case, xhci_alloc_dev() creates debugfs entries upon an existing device without cleaning up old entries, thus memory leaks. So this patch simply moves calling xhci_debugfs_free_dev() from xhci_free_dev() to xhci_disable_slot(). [added "possible" to header as this is about failure codepath -Mathias] Signed-off-by:

If the 'kmalloc()' fails, we need to undo the previous 'dbc_alloc_request()' call. Because of the more similar function name, it is more logical to use 'dbc_free_request()' instead of 'xhci_dbc_free_req()'. Both are equivalent here because: static void xhci_dbc_free_req(struct dbc_ep *dep, struct dbc_request *req) { kfree(req->buf); dbc_free_request(dep, req); } and 'req->buf' is known to be NULL at this point Signed-off-by: -

Currently the check on a non-zero return code in ret is false because ret has been initialized to zero. I believe that ret should be assigned to the return from the call to readl_poll_timeout_atomic before the check on ret. Since ret is being re-assinged the original initialization of ret to zero can be removed.
