The same shape in 4 drivers, so they are here as one series. Affected: aiu, axg-pdm, axg-spdifin, axg-spdifout. The fix is a select rather than a depends on: the providers have no prompt of their own and are only ever enabled by a select, so a depends on would leave these drivers unselectable. Each was reproduced on v7.3, arm64 by a vmlinux link that failed on the named symbol, and each links once the select is added. Found with kreach, a static check that compares what Kconfig allows against the symbols the compiled objects actually reference. The checker is at https://github.com/JGyimah/kreach, and the reproducer configuration for each finding is published with it under results/.
