6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quan Zhou <zhouquan@xxxxxxxxxxx>
[ Upstream commit c66f3b40b17d3dfc4b6abb5efde8e71c46971821 ]
In the function kvm_riscv_vcpu_set_reg_isa_ext, the original code
used incorrect reg_subtype labels KVM_REG_RISCV_SBI_MULTI_EN/DIS.
These have been corrected to KVM_REG_RISCV_ISA_MULTI_EN/DIS respectively.
Although they are numerically equivalent, the actual processing
will not result in errors, but it may lead to ambiguous code semantics.
