Description

In the Linux kernel, the following vulnerability has been resolved: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER In create_pinctrl(), pinctrl_maps_mutex is acquired before calling add_setting(). If add_setting() returns -EPROBE_DEFER, create_pinctrl() calls pinctrl_free(). However, pinctrl_free() attempts to acquire pinctrl_maps_mutex, which is already held by create_pinctrl(), leading to a potential deadlock. This patch resolves the issue by releasing pinctrl_maps_mutex before calling pinctrl_free(), preventing the deadlock. This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
