powerpc/pseries: Remove unused r0 in the hcall tracing code
In the plpar_hcall trace code, currently we use r0 to store the value of r4. But this value is not used subsequently in the code. Hence remove this unused save to r0 in plpar_hcall and plpar_hcall9 Suggested-by: Naveen N Rao <naveen@kernel.org> Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://msgid.link/20230929172337.7906-2-atrajeev@linux.vnet.ibm.com
