Refactor the code and remove the cscen variable to convince gcc that we are doing a good job. drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c:218:20: warning: 'coeffs' may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Ricardo Ribalda Reviewed-by: Laurent Pinchart Link: https://lore.kernel.org/r/20240128-gcc-11-warnings-v1-1-52bbdf492049@chromium.org Signed-off-by: Laurent Pinchart Signed-off-by: Hans Verkuil --- diff --git a/drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c b/drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c index 19e80b95ffeaa..5623914f95e64 100644 --- a/drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c +++ b/drivers/media/platform/nxp/imx8-isi/imx8-isi-hw.c @@ -215,8 +215,7 @@ static void mxc_isi_channel_set_csc(struct mxc_isi_pipe *pipe, [MXC_ISI_ENC_RGB] = "RGB", [MXC_ISI_ENC_YUV] = "YUV", }; - const u32 *coeffs; - bool cscen = true; + const u32 *coeffs = NULL; u32 val; val = mxc_isi_read(pipe, CHNL_IMG_CTRL); @@ -235,14 +234,13 @@ static void mxc_isi_channel_set_csc(struct mxc_isi_pipe *pipe, val |= CHNL_IMG_CTRL_CSC_MODE(CHNL_IMG_CTRL_CSC_MODE_RGB2YCBCR); } else { /* Bypass CSC */ - cscen = false; val |= CHNL_IMG_CTRL_CSC_BYPASS; } dev_dbg(pipe->isi->dev, "CSC: %s -> %s\n", encodings[in_encoding], encodings[out_encoding]); - if (cscen) { + if (coeffs) { mxc_isi_write(pipe, CHNL_CSC_COEFF0, coeffs[0]); mxc_isi_write(pipe, CHNL_CSC_COEFF1, coeffs[1]); mxc_isi_write(pipe, CHNL_CSC_COEFF2, coeffs[2]); @@ -253,7 +251,7 @@ static void mxc_isi_channel_set_csc(struct mxc_isi_pipe *pipe, mxc_isi_write(pipe, CHNL_IMG_CTRL, val); - *bypass = !cscen; + *bypass = !coeffs; } void mxc_isi_channel_set_alpha(struct mxc_isi_pipe *pipe, u8 alpha)
