Found this going over intel_bios.c and cross comparing it with the Intel/IMG driver intel_bios.c
temp_mode = kzalloc(sizeof(*temp_mode), GFP_KERNEL); temp_downclock = panel_fixed_mode->clock; /* * enumerate the LVDS panel timing info entry in VBT to check whether * the LVDS downclock is found. */ for (i = 0; i < 16; i++) { entry = (struct bdb_lvds_lfp_data_entry *) ((uint8_t *)lvds_lfp_data->data + (lfp_data_size * i)); dvo_timing = (struct lvds_dvo_timing *) ((unsigned char *)entry + dvo_timing_offset);
fill_detail_timing_data(temp_mode, dvo_timing);
The one for IMG devices (GMA500 etc) has an additional unchecked kmalloc which the i915 driver has fixed.
