The 's' is from the '%s' format specifier:

[ 2610.804174] imx-nwl-dsi 30a00000.mipi_dsi: [drm:imx_nwl_dsi_bridge_disable] disabling platform clocks
[ 2710.996279] imx-nwl-dsi 30a00000.mipi_dsi: [drm:imx_nwl_dsi_bridge_pre_enable] enabling platform clocks

I'll change that to use the full strings though since i also had to look
twice to be sure there's no double 's'.
