## Description

In the Linux kernel, the following vulnerability has been resolved: pinctrl: canaan: k230: add NULL check in DT parse Add a NULL check for the return value of of_get_property() when retrieving the "pinmux" property in the group parser. This avoids a potential NULL pointer dereference if the property is missing from the device tree node. Also fix a typo ("sintenel") in the device ID match table comment, correcting it to "sentinel".
