GHSA-gw9v-f3c7-qfqv 
In the Linux kernel, the following vulnerability has been resolved:ice: fix uninitialized dplls mutex usageThe 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
