[igt-dev] [PATCH i-g-t 3/4] lib/igt_edid: make HDMI VSDB data array unsigned

[Simon Ser]

This array is filled manually, some bytes might have the MSB set.

This fixes the following warning:

    ../lib/igt_kms.c:357:18: warning: implicit conversion from 'int' to 'char' changes value from 128 to -128 [-Wconstant-conversion]
            hdmi->data[0] = HDMI_VSDB_VIDEO_3D_PRESENT; /* HDMI video flags */
    	                      ~ ^~~~~~~~~~~~~~~~~~~~~~~~~~
