This warning is caused by not having the fixup patch "riscv: Replace 
function-like macro by static inline function" upstream commit 
121f34341d396b666d8a90b24768b40e08ca0d61 in 6.6.89-rc1, 6.1.136-rc1 and 
5.15.181-rc1. Looks like it didn't apply cleanly to those versions.

The fixup patch was included in 6.14.5-rc1 and 6.12.26-rc1.
