+
+commit 88a173e5dd05e788068e8fa20a8c37c44bd8f416 upstream.
+
+Currently async flips are busted when bigjoiner is in use.
+As a short term fix simply reject async flips in that case.

+Subject: Input: soc_button_array - add mapping for airplane mode button
+
+From: Christoffer Sandberg <cs@tuxedo.de>
+
+commit ea3715941a9b7d816a1e9096ac0577900af2a69e upstream.
+
+This add a mapping for the airplane mode button on the TUXEDO Pulse Gen3.
+
+While it is physically a key it behaves more like a switch, sending a key
+down on first press and a key up on 2nd press. Therefor the switch event
+is used here. Besides this behaviour it uses the HID usage-id 0xc6
+(Wireless Radio Button) and not 0xc8 (Wireless Radio Slider Switch), but
+since neither 0xc6 nor 0xc8 are currently implemented at all in
+soc_button_array this not to standard behaviour is not put behind a quirk
+for the moment.

+Subject: net: 9p: avoid freeing uninit memory in p9pdu_vreadf
+
+From: Fedor Pchelkin <pchelkin@ispras.ru>
+
+commit ff49bf1867578f23a5ffdd38f927f6e1e16796c4 upstream.
+
+If some of p9pdu_readf() calls inside case 'T' in p9pdu_vreadf() fails,
+the error path is not handled properly. *wnames or members of *wnames
+array may be left uninitialized and invalidly freed.
+
+Initialize *wnames to NULL in beginning of case 'T'. Initialize the first
+*wnames array element to NULL and nullify the failing *wnames element so
+that the error path freeing loop stops on the first NULL element and
+doesn't proceed further.
+
+Found by Linux Verification Center (linuxtesting.org).

+Subject: net: rfkill: gpio: set GPIO direction
+
+From: Rouven Czerwinski <r.czerwinski@pengutronix.de>
+
+commit 23484d817082c3005252d8edfc8292c8a1006b5b upstream.
+
+Fix the undefined usage of the GPIO consumer API after retrieving the
+GPIO description with GPIO_ASIS. The API documentation mentions that
+GPIO_ASIS won't set a GPIO direction and requires the user to set a
+direction before using the GPIO.
+
+This can be confirmed on i.MX6 hardware, where rfkill-gpio is no longer
+able to enabled/disable a device, presumably because the GPIO controller
+was never configured for the output direction.
