Thanks Will, we will double check this.
It is false positive. Please ignore this
issue. Sorry for inconvenient.
This build failure is caused by commit "RISC-V: Add kconfig option for QEMU virt
machine" and already been fixed by commit "RISC-V: Only select essential drivers
for SOC_VIRT config" in v5.6 but not in Peter's queue at that moment. These
failure log should be ignored by bisect for this patch. We will enhance the bisect logic.
Thanks.
