+Subject: hwmon: (pwm-fan) Disable PWM if fetching cooling data fails
+
+From: Stefan Wahren <stefan.wahren@i2se.com>
+
+commit 53f1647da3e8fb3e89066798f0fdc045064d353d upstream.
+
+In case pwm_fan_of_get_cooling_data() fails we should disable the PWM
+just like in the other error cases.

+Subject: platform/x86: sony-laptop: Fix unintentional fall-through
+
+From: Gustavo A. R. Silva <gustavo@embeddedor.com>
+
+commit 1cbd7a64959d33e7a2a1fa2bf36a62b350a9fcbd upstream.
+
+It seems that the default case should return AE_CTRL_TERMINATE, instead
+of falling through to case ACPI_RESOURCE_TYPE_END_TAG and returning AE_OK;
+otherwise the line of code at the end of the function is unreachable and
+makes no sense:
+
+return AE_CTRL_TERMINATE;
+
+This fix is based on the following thread of discussion:
+
+https://lore.kernel.org/patchwork/patch/959782/

+Subject: platform/x86: thinkpad_acpi: Disable Bluetooth for some machines
+
+From: Jiaxun Yang <jiaxun.yang@flygoat.com>
+
+commit f7db839fccf087664e5587966220821289b6a9cb upstream.
+
+Some AMD based ThinkPads have a firmware bug that calling
+"GBDC" will cause Bluetooth on Intel wireless cards blocked.
+
+Probe these models by DMI match and disable Bluetooth subdriver
+if specified Intel wireless card exist.
