pinctrl: pinctrl_stm32: Fix warnings when compiling with W=1
This patch solves the following warnings: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits] if (*idx < 0) ^ drivers/pinctrl/pinctrl_stm32.c: At top level: warning: no previous prototype for 'stm32_pinctrl_probe' [-Wmissing-prototypes] int stm32_pinctrl_probe(struct udevice *dev) ^~~~~~~~~~~~~~~~~~~ Signed-off-by: Patrice CHOTARD <patrice.chotard@st.com> Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
