The rza1_mux_conf object pointed to by the mux_conf parameter of rza1_pin_mux_single() is never modified. Make it const. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- This has a small conflict with "[PATCH v4 09/15] pinctrl: constify pinmux_generic_get_function()"[1], which I have already acked. Perhaps the best solution is for Bartosz to include this in his series? Or I can resend an updated version for LinusW to apply after Bartosz series has handled? Thanks!
