+Subject: ALSA: cs4236: fix an incorrect NULL check on list iterator
+
+From: Xiaomeng Tong <xiam0nd.tong@gmail.com>
+
+commit 0112f822f8a6d8039c94e0bc9b264d7ffc5d4704 upstream.
+
+The bug is here:
+ err = snd_card_cs423x_pnp(dev, card->private_data, pdev, cdev);
+
+The list iterator value 'cdev' will *always* be set and non-NULL
+by list_for_each_entry(), so it is incorrect to assume that the
+iterator value will be NULL if the list is empty or no element
+is found.
+
+To fix the bug, use a new variable 'iter' as the list iterator,
+while use the original variable 'cdev' as a dedicated pointer
+to point to the found element. And snd_card_cs423x_pnp() itself
+has NULL check for cdev.

+Subject: ALSA: hda/realtek: Fix audio regression on Mi Notebook Pro 2020
+
+From: Kai-Heng Feng <kai.heng.feng@canonical.com>
+
+commit f30741cded62f87bb4b1cc58bc627f076abcaba8 upstream.
+
+Commit 5aec98913095 ("ALSA: hda/realtek - ALC236 headset MIC recording
+issue") is to solve recording issue met on AL236, by matching codec
+variant ALC269_TYPE_ALC257 and ALC269_TYPE_ALC256.
+
+This match can be too broad and Mi Notebook Pro 2020 is broken by the
+patch.
+
+Instead, use codec ID to be narrow down the scope, in order to make
+ALC256 unaffected.

+Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=215484

+Subject: Revert "Input: clear BTN_RIGHT/MIDDLE on buttonpads"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: José Expósito <jose.exposito89@gmail.com>
+
+commit 8b188fba75195745026e11d408e4a7e94e01d701 upstream.
+
+This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
+
+The touchpad present in the Dell Precision 7550 and 7750 laptops
+reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
+the device is not a clickpad, it is a touchpad with physical buttons.
+
+In order to fix this issue, a quirk for the device was introduced in
+libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
+
+ [Precision 7x50 Touchpad]
+ MatchBus=i2c
+ MatchUdevType=touchpad
+ MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
+ AttrInputPropDisable=INPUT_PROP_BUTTONPAD
+
+However, because of the change introduced in 37ef4c19b4 ("Input: clear
+BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
+anymore breaking the device right click button and making impossible to
+workaround it in user space.
+
+In order to avoid breakage on other present or future devices, revert
+the patch causing the issue.
