Subject: [PATCH] soc: renesas: select ERRATA_ANDES for R9A07G043 only when alternatives are present
Date: Mon, 9 Oct 2023 09:11:16 +0100 [thread overview]
Message-ID: <20231009-sandbar-botch-0f398fd2e289@wendy> (raw)
Randy reported a randconfig build issue against linux-next:
WARNING: unmet direct dependencies detected for ERRATA_ANDES
Depends on [n]: RISCV_ALTERNATIVE [=n] && RISCV_SBI [=y]
Selected by [y]:
- ARCH_R9A07G043 [=y] && SOC_RENESAS [=y] && RISCV [=y] && NONPORTABLE [=y] && RISCV_SBI [=y]
../arch/riscv/errata/andes/errata.c:59:54: warning: 'struct alt_entry' declared inside parameter list will not be visible outside of this definition or declaration
59 | void __init_or_module andes_errata_patch_func(struct alt_entry *begin, struct alt_entry *end,
On RISC-V, alternatives are not usable in XIP kernels, which this
randconfig happened to select. Add a check for whether alternatives are
available before selecting the ERRATA_ANDES config option.
