Pull USB/PHY updates from Greg KH:
 "Here is the big USB/PHY driver pull request for 5.1-rc1.

  The usual set of gadget driver updates, phy driver updates, xhci
  updates, and typec additions. Also included in here are a lot of small
  cleanups and fixes and driver updates where needed.

  All of these have been in linux-next for a while with no reported
  issues"

Make the default autosuspend delay configurable at build time.
This is useful for systems that require a non-standard value as
it avoids relying on the command line being properly set.

On Chrome OS we want to use USBguard to potentially limit access to USB
devices based on policy. We however to do not want to wait for userspace to
come up before initializing fixed USB devices to not regress our boot
times.

This patch adds option to instruct the kernel to only authorize devices
connected to the internal ports. Previously we could either authorize
all or none (or, by default, we'd only authorize wired devices).

The behavior is controlled via usbcore.authorized_default command line
option.

Expression (urb->transfer_flags & URB_DIR_MASK) == URB_DIR_IN can be
replaced by usb_urb_dir_in(struct urb *urb) from usb.h for better
readability.

If an interface has an associated devicetree node with status disabled,
do not register the device.  This is useful for boards with a built-in
multifunction USB device where some functions are broken or otherwise
undesired.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

Notice that, in this case, variable len is not necessary, hence
it is removed.

This code was detected with the help of Coccinelle.

Commit f13912d3f014a introduced changes to the usb_choose_configuration function
to better support USB Audio UAC3-compatible devices. However, there are a few
problems with this patch. First of all, it adds new "if" clauses in the middle
of an existing "if"/"else if" tree, which obviously breaks pre-existing logic.
Secondly, since it continues iterating over configurations in one of the branches,
other code in the loop can choose an unintended configuration. Finally,
if an audio device's first configuration is UAC3-compatible, and there
are multiple UAC3 configurations, the second one would be chosen, due to
the first configuration never being checked for UAC3-compatibility.

Commit ff2a8c532c14 tries to fix the second issue, but it goes about it in a
somewhat unnecessarily convoluted way, in my opinion, and does nothing
to fix the first or the last one.

This patch tries to rectify problems described by essentially rewriting
code introduced in f13912d3f014a. Notice the code was moved to *before*
the "if"/"else if" tree.

On plug-in of my USB-C device, its USB_SS_PORT_LS_SS_INACTIVE
link state bit is set. Greping all the kernel for this bit shows
that the port status requests a warm-reset this way.

This just happens, if its the only device on the root hub, the hub
therefore resumes and the HCDs status_urb isn't yet available.
If a warm-reset request is detected, this sets the hubs event_bits,
which will prevent any auto-suspend and allows the hubs workqueue
to warm-reset the port later in port_event.
