Start by checking the reported symlinks /techpack/audio/soc/core.h and /techpack/audio/soc/pinctrl-utils.h, then inspect the missing soc/internal.h references in the listed C files. Reproduce the build failure and determine whether the symlinks and the undefined msm_ext_disp_register_audio_codec reference are resolved; a successful vmlinux build is the stated goal.
