configname: CONFIG_FW_CACHE

└─>Enable firmware caching during suspend
In linux kernel since version 4.14.326 (release Date: 2023-09-23)  
Because firmware caching generates uevent messages that are sent
over a netlink socket, it can prevent suspend on many platforms.
It is also not always useful, so on such platforms we have the
option.

If unsure, say Y.
