Make sure we have at least one port before attempting to register a console. Currently, at least one driver binds to a "dummy" interface and requests zero ports for it. Should such an interface also lack endpoints, we get a NULL-deref during probe.

USB2 host inititated resume, and system suspend bus resume need to use the same USB_RESUME_TIMEOUT as elsewhere. This resolves a device disconnect issue at system resume seen on Intel Braswell and Apollolake, but is in no way limited to those platforms. Signed-off-by:

If a device is unplugged and replugged during Sx system suspend some Intel xHC hosts will overwrite the CAS (Cold attach status) flag and no device connection is noticed in resume. A device in this state can be identified in resume if its link state is in polling or compliance mode, and the current connect status is 0. A device in this state needs to be warm reset. Intel 100/c230 series PCH specification update Doc #332692-006 Errata #8 Observed on Cherryview and Apollolake as they go into compliance mode if LFPS times out during polling, and re-plugged devices are not discovered at resume.

Nothing major this time around. The most important patches are the 3 fixes in dwc3 (dma_free_coheren() size fix, queued request accounting fix and Isochronous StartTransfer fix) and the 3 reverts on dwc2. We're also including the late atmel UDC fix which didn't make it into v4.8-final.

This reverts commit aa381a72 ("usb: dwc2: gadget: fix TX FIFO size and address initialization"). The original commit removed the FIFO size programming per endpoint. The DPTXFSIZn register is also used for DIEPTXFn and the SIZE field is r/w in dedicated fifo mode. So it isn't appropriate to simply remove this initialization as it might break existing behavior. Also, some cores might not have enough fifo space to handle the programming method used in the reverted patch, resulting in fifo initialization failure. Signed-off-by:

Change thaw_super() to check frozen != SB_FREEZE_COMPLETE rather than frozen == SB_UNFROZEN, otherwise it can race with freeze_super() which drops sb->s_umount after SB_FREEZE_WRITE to preserve the lock ordering. In this case thaw_super() will wrongly call s_op->unfreeze_fs() before it was actually frozen, and call sb_freeze_unlock() which leads to the unbalanced percpu_up_write(). Unfortunately lockdep can't detect this, so this triggers misc BUG_ON()'s in kernel/rcu/sync.c. Reported-and-tested-by:

ovl_fill_super calls ovl_new_inode to create a root inode for the new superblock before initializing sb->s_xattr. This wrongly causes IOP_XATTR to be cleared in i_opflags of the new inode, causing SELinux to log the following message: SELinux: (dev overlay, type overlay) has no xattr support Fix this by initializing sb->s_xattr and similar fields before calling ovl_new_inode.

Both import_iovec() and rw_copy_check_uvector() take an array (typically small and on-stack) which is used to hold an iovec array copy from userspace. This is to avoid an expensive memory allocation in the fast path (i.e. few iovec elements). The caller may have to check whether these functions actually used the provided buffer or allocated a new one -- but this differs between the too. Let's just add a kernel doc to clarify what the semantics are for each function. Signed-off-by:
