+Subject: ALSA: usb-audio: Add delay quirk for USB Audio Device
+
+From: Lianqin Hu <hulianqin@vivo.com>
+
+commit ad5b205f9e022b407d91f952faddd05718be2866 upstream.
+
+Audio control requests that sets sampling frequency sometimes fail on
+this card. Adding delay between control messages eliminates that problem.
+
+usb 1-1: New USB device found, idVendor=0d8c, idProduct=0014
+usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
+usb 1-1: Product: USB Audio Device
+usb 1-1: Manufacturer: C-Media Electronics Inc.

+Subject: Input: atkbd - map F23 key to support default copilot shortcut
+
+From: Mark Pearson <mpearson-lenovo@squebb.ca>
+
+commit 907bc9268a5a9f823ffa751957a5c1dd59f83f42 upstream.
+
+Microsoft defined Meta+Shift+F23 as the Copilot shortcut instead of a
+dedicated keycode, and multiple vendors have their keyboards emit this
+sequence in response to users pressing a dedicated "Copilot" key.
+Unfortunately the default keymap table in atkbd does not map scancode
+0x6e (F23) and so the key combination does not work even if userspace
+is ready to handle it.
+
+Because this behavior is common between multiple vendors and the
+scancode is currently unused map 0x6e to keycode 193 (KEY_F23) so that
+key sequence is generated properly.
+
+MS documentation for the scan code:
+https://learn.microsoft.com/en-us/windows/win32/inputdev/about-keyboard-input#scan-codes
+Confirmed on Lenovo, HP and Dell machines by Canonical.
+Tested on Lenovo T14s G6 AMD.

+
+commit 66372fa9936088bf29c4f47907efeff03c51a2c8 upstream.
+
+8BitDo Pro 2 Wired Controller shares the same USB identifier
+(2dc8:3106) as a different device, so amend name to reflect that and
+reduce confusion as the user might think the controller was misdetected.
+
+Because Pro 2 Wired will not work in XTYPE_XBOXONE mode (button presses
+won't register), tagging it as XTYPE_XBOX360 remains appropriate.

+Subject: USB: serial: quatech2: fix null-ptr-deref in qt2_process_read_urb()
+
+From: Qasim Ijaz <qasdev00@gmail.com>
+
+commit 575a5adf48b06a2980c9eeffedf699ed5534fade upstream.
+
+This patch addresses a null-ptr-deref in qt2_process_read_urb() due to
+an incorrect bounds check in the following:
+
+ if (newport > serial->num_ports) {
+ dev_err(&port->dev,
+ "%s - port change to invalid port: %i\n",
+ __func__, newport);
+ break;
+ }
+
+The condition doesn't account for the valid range of the serial->port
+buffer, which is from 0 to serial->num_ports - 1. When newport is equal
+to serial->num_ports, the assignment of "port" in the
+following code is out-of-bounds and NULL:
+
+ serial_priv->current_port = newport;
+ port = serial->port[serial_priv->current_port];
+
+The fix checks if newport is greater than or equal to serial->num_ports
+indicating it is out-of-bounds.
