Hi,
Smatch warns:
drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c:755
dw_mipi_dsi_rockchip_set_lcdsel() warn: unsigned
'dsi->cdata->lcdsel_grf_reg'
is never less than zero.
static void dw_mipi_dsi_rockchip_set_lcdsel(struct dw_mipi_dsi_rockchip
*dsi,
int mux)
{
if (dsi->cdata->lcdsel_grf_reg < 0)
regmap_write(dsi->grf_regmap, dsi->cdata->lcdsel_grf_reg,
mux ? dsi->cdata->lcdsel_lit :
dsi->cdata->lcdsel_big);
}
'dsi->cdata->lcdsel_grf_reg' is of u32 type, it can never be less than zero.
So the above if condition is an impossible one.
Note: 'lcdsel_grf_reg' is set to -1 at other places.
Thanks,
Harshit
