Subject: [PATCH] clk: renesas: rcar-gen3: Update Z clock rate formula in comments
Git-commit: 192c344e7cd4e19a4260752604ba219ffa41deb1
Patch-mainline: v5.14-rc1
References: git-fixes

The fixed divider in the calculation of the Z and Z2 clock rates was
generalized from a hardcoded value of two to a parameterized value, but
the comments were not updated accordingly.

Fixes: 20cc05ba04a93f05 ("clk: renesas: rcar-gen3: Parameterise Z and Z2 clock fixed divisor")
