Use int as result of dm_i2c_reg_read to avoid warning with W=1 (warning: comparison is always false due to limited range of data type [-Wtype-limits]) Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com> --- drivers/pinctrl/pinctrl-stmfx.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-)
