bbilas · fabiobaltieri · commit 22ebd564077b · 2026-05-18T15:24:45.000+01:00
Add a guard for `eth_esp32_iomux_rmii_clk_input` function to fix the
following error:

error: 'eth_esp32_iomux_rmii_clk_input' defined but not used
[-Werror=unused-function] 245 | static void
eth_esp32_iomux_rmii_clk_input(void)
