+Subject: gpio: tb10x: Fix an error handling path in tb10x_gpio_probe()
+
+From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
+
+[ Upstream commit b547b5e52a0587e6b25ea520bf2f9e03d00cbcb6 ]
+
+If an error occurs after a successful irq_domain_add_linear() call, it
+should be undone by a corresponding irq_domain_remove(), as already done
+in the remove function.

+Subject: i2c: mux: demux-pinctrl: check the return value of devm_kstrdup()
+
+From: Xiaoke Wang <xkernel.wang@foxmail.com>
+
+[ Upstream commit 7c0195fa9a9e263df204963f88a22b21688ffb66 ]
+
+devm_kstrdup() returns pointer to allocated string on success,
+NULL on failure. So it is better to check the return value of it.
