CVE-2024-36940

In the Linux kernel, the following vulnerability has been resolved:

pinctrl: core: delete incorrect free in pinctrl_enable()

The "pctldev" struct is allocated in devmpinctrlregisterandinit(). It's a devm_ managed pointer that is freed by devmpinctrldevrelease(), so freeing it in pinctrlenable() will lead to a double free.

The devmpinctrldev_release() function frees the pindescs and destroys the mutex as well.
