+Subject: usb: renesas_usbhs: protect the CFIFOSEL setting in usbhsg_ep_enable()
+
+From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
+
+commit 15e4292a2d21e9997fdb2b8c014cc461b3f268f0 upstream.
+
+This patch fixes an issue that the CFIFOSEL register value is possible
+to be changed by usbhsg_ep_enable() wrongly. And then, a data transfer
+using CFIFO may not work correctly.
+
+For example:
+ # modprobe g_multi file=usb-storage.bin
+ # ifconfig usb0 192.168.1.1 up
+ (During the USB host is sending file to the mass storage)
+ # ifconfig usb0 down
+
+In this case, since the u_ether.c may call usb_ep_enable() in
+eth_stop(), if the renesas_usbhs driver is also using CFIFO for
+mass storage, the mass storage may not work correctly.
+
+So, this patch adds usbhs_lock() and usbhs_unlock() calling in
+usbhsg_ep_enable() to protect CFIFOSEL register. This is because:
+ - CFIFOSEL.CURPIPE = 0 is also needed for the pipe configuration
+ - The CFIFOSEL (fifo->sel) is already protected by usbhs_lock()
+
+Fixes: 97664a207bc2 ("usb: renesas_usbhs: shrink spin lock area")

+Subject: USB: serial: option: add support for Telit LE910 PID 0x1206
+
+From: Daniele Palmas <dnlplm@gmail.com>
+
+commit 3c0415fa08548e3bc63ef741762664497ab187ed upstream.
+
+This patch adds support for 0x1206 PID of Telit LE910.
+
+Since the interfaces positions are the same than the ones for
+0x1043 PID of Telit LE922, telit_le922_blacklist_usbcfg3 is used.
