Re: [PATCH v15 3/3] media: i2c: Add support for alvium camera

[Tommaso Merciai]

Hi Sakari,
Just a clarification about the following warnings:

Fixed on my side with:

CHECK: Assignment operator '=' should be on the previous line

-       alvium->is_mipi_fmt_avail[ALVIUM_BIT_YUV420_8_LEG]
-                                 = avail_fmt->yuv420_8_leg;
+       alvium->is_mipi_fmt_avail[ALVIUM_BIT_YUV420_8_LEG] =
+                                 avail_fmt->yuv420_8_leg;

CHECK: line length of 81 exceeds 80 columns
#1085: FILE: drivers/media/i2c/alvium-csi2.c:1085:
+		if (!alvium->is_mipi_fmt_avail[alvium_csi2_fmts[fmt].fmt_av_bit])

CHECK: line length of 81 exceeds 80 columns
#1102: FILE: drivers/media/i2c/alvium-csi2.c:1102:
+		if (!alvium->is_mipi_fmt_avail[alvium_csi2_fmts[fmt].fmt_av_bit])


Fixed on my side with:

        /* Create the alvium_csi2 fmt array from formats available */
        for (fmt = 0; fmt < ALVIUM_NUM_SUPP_MIPI_DATA_FMT; fmt++) {
-               if (!alvium->is_mipi_fmt_avail[alvium_csi2_fmts[fmt].fmt_av_bit])
+               if (!alvium->is_mipi_fmt_avail[alvium_csi2_fmts[fmt]
+                               .fmt_av_bit])
                        continue;

Can be ok for you?
If yes I'm going to prepare the patch on top of your media_tree/master
branch.

Thanks & Regards,
Tommaso
