+Subject: ALSA: line6: Perform sanity check for each URB creation
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 6e8a914ad619042c5f25a4feb663357c4170fd8d upstream.
+
+LINE6 drivers create stream URBs with a fixed pipe without checking
+its validity, and this may lead to a kernel WARNING at the submission
+when a malformed USB descriptor is passed.
+
+For avoiding the kernel warning, perform the similar sanity checks for
+each pipe type at creating a URB.

+Subject: ALSA: usb-audio: Fix race against the error recovery URB submission
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 9b7e5208a941e2e491a83eb5fa83d889e888fa2f upstream.
+
+USB MIDI driver has an error recovery mechanism to resubmit the URB in
+the delayed timer handler, and this may race with the standard start /
+stop operations. Although both start and stop operations themselves
+don't race with each other due to the umidi->mutex protection, but
+this isn't applied to the timer handler.
+
+For fixing this potential race, the following changes are applied:
+
+- Since the timer handler can't use the mutex, we apply the
+ umidi->disc_lock protection at each input stream URB submission;
+ this also needs to change the GFP flag to GFP_ATOMIC
+- Add a check of the URB refcount and skip if already submitted
+- Move the timer cancel call at disconnection to the beginning of the
+ procedure; this assures the in-flight timer handler is gone properly
+ before killing all pending URBs

+Subject: usb: core: Add a helper function to check the validity of EP type in URB
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit e901b9873876ca30a09253731bd3a6b00c44b5b0 upstream.
+
+This patch adds a new helper function to perform a sanity check of the
+given URB to see whether it contains a valid endpoint. It's a light-
+weight version of what usb_submit_urb() does, but without the kernel
+warning followed by the stack trace, just returns an error code.
+
+Especially for a driver that doesn't parse the descriptor but fills
+the URB with the fixed endpoint (e.g. some quirks for non-compliant
+devices), this kind of check is preferable at the probe phase before
+actually submitting the urb.

+Apparently, it's a regular CH340, but I've confirmed with others that
+also bought this board that the PID found on this device (0x7522)
+differs from other devices with the "same" converter (0x7523).
+Simply adding its PID to the driver and rebuilding it made it work
+as expected.

+Subject: USB: serial: cypress_m8: enable Simply Automated UPB PIM
+
+From: James Hilliard <james.hilliard1@gmail.com>
+
+commit 5c45d04c5081c1830d674f4d22d4400ea2083afe upstream.
+
+This is a UPB (Universal Powerline Bus) PIM (Powerline Interface Module)
+which allows for controlling multiple UPB compatible devices from Linux
+using the standard serial interface.
+
+Based on vendor application source code there are two different models
+of USB based PIM devices in addition to a number of RS232 based PIM's.
+
+The vendor UPB application source contains the following USB ID's:
+
+ #define USB_PCS_VENDOR_ID 0x04b4
+ #define USB_PCS_PIM_PRODUCT_ID 0x5500
+
+ #define USB_SAI_VENDOR_ID 0x17dd
+ #define USB_SAI_PIM_PRODUCT_ID 0x5500
+
+The first set of ID's correspond to the PIM variant sold by Powerline
+Control Systems while the second corresponds to the Simply Automated
+Incorporated PIM. As the product ID for both of these match the default
+cypress HID->COM RS232 product ID it assumed that they both use an
+internal variant of this HID->COM RS232 converter hardware. However
+as the vendor ID for the Simply Automated variant is different we need
+to also add it to the cypress_M8 driver so that it is properly
+detected.

+
+From: Johan Hovold <johan@kernel.org>
+
+commit e7b931bee739e8a77ae216e613d3b99342b6dec0 upstream.
+
+The driver would happily overwrite its write buffer with user data in
+256 byte increments due to a removed buffer-space sanity check.
