+Subject: ALSA: usb-audio: Apply the sample rate quirk for Bose Companion 5
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 51d4efab7865e6ea6a4ebcd25b3f03c019515c4c upstream.
+
+Bose Companion 5 (with USB ID 05a7:1020) doesn't seem supporting
+reading back the sample rate, so the existing quirk is needed.

+Subject: usb: chipidea: host: Disable port power only if previously enabled
+
+From: Guenter Roeck <linux@roeck-us.net>
+
+commit c1ffba305dbcf3fb9ca969c20a97acbddc38f8e9 upstream.
+
+On shutdown, ehci_power_off() is called unconditionally to power off
+each port, even if it was never called to power on the port.
+For chipidea, this results in a call to ehci_ci_portpower() with a request
+to power off ports even if the port was never powered on.
+This results in the following warning from the regulator code.
+
+WARNING: CPU: 0 PID: 182 at drivers/regulator/core.c:2596 _regulator_disable+0x1a8/0x210

+Keeping track of the power enable state avoids the warning and traceback.
