riscv: dead code cleanup in kconfig for RISCV_PROBE_VECTOR_UNALIGNED_ACCESS

[PATCH] riscv: dead code cleanup in kconfig for RISCV_PROBE_VECTOR_UNALIGNED_ACCESS

Posted by Julian Braha 3 days, 13 hours ago

The same Kconfig statement 'depends on RISCV_ISA_V' appears twice for
RISCV_PROBE_VECTOR_UNALIGNED_ACCESS. The first instance is in its choice
menu, "Vector unaligned Accesses Support", making the second instance in
its specific Kconfig definition dead code. I propose removing this second
instance.

This dead code was found by kconfirm, a static analysis tool for Kconfig.
