+Subject: [PATCH 0/7] revert series of drivers/bluetooth/hci commits to fix Galileo/OLED Deck + Legion Go failing to suspend on 6.8 kernels
+
+Revert series of commits that causes a bluetooth regression where toggling Bluetooth on the Galileo/OLED Deck and Legion Go can cause the device to fail to suspend properly. Instead, the display turns dims for 5-10s before waking up automatically again.
+
+Logs show:
+
+"Failed to add UUID: Failed (0x03)"
+"Failed to set mode: Authentication Failed (0x05)"
+
+hci0: Retry BT power ON:0
+hci0: command tx timeout
+hci0: Reading QCA version information failed (-110)
+
+`sudo rmmod hci_uart` was a workaround, while this patch removes the need for that until it is sorted out upstream.
+
+Matthew Schwartz (7):
+ Revert "Bluetooth: qca: fix device-address endianness"
+ Reapply "Bluetooth: hci_qca: Set BDA quirk bit if fwnode exists in DT"
+ Revert "Bluetooth: btrtl: fix out of bounds memory access"
+ Revert "Bluetooth: hci_h5: Add ability to allocate memory for private
+ data"
+ Revert "Bluetooth: hci_qca: don't use IS_ERR_OR_NULL() with
+ gpiod_get_optional()"
