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

ice: fix uninitialized dplls mutex usage

The pf->dplls.lock mutex is initialized too late, after its first use.

Move it to the top of ice_dpll_init.

Note that the "err_exit" error path destroys the mutex. And the mutex is

the last thing destroyed in ice_dpll_deinit.

This fixes the following warning with CONFIG_DEBUG_MUTEXES:

ice 0000:10:00.0: The DDP package was successfully loaded: ICE OS Default Package version 1.3.36.0

ice 0000:10:00.0: 252.048 Gb/s available PCIe bandwidth (16.0 GT/s PCIe x16 link)

ice 0000:10:00.0: PTP init successful
