This is fixed for hirsute (checked with linux and linux-riscv) by the following commit:

[ Upstream commit d452d48b9f8b1a7f8152d33ef52cfd7fe1735b0a ]

The 5.8 kernels (checked with focal/linux-hwe-5.8) is still affected. But given that the 5.8 kernels are not receiving upstream stable updates anymore this issue will likely not be fixed.
