The dmi_walk function maps the DMI table, walks it, and unmaps it. This means that the dell_bios_hotkey_table that find_hk_type stores points to unmapped memory by the time it gets read. I've been able to trigger crashes caused by the stale pointer a couple of times, but never on a stock kernel. Fix it by generating the keymap in the dmi_walk callback instead of storing a pointer.
