The IEEE OUI begins at the byte after the type/length byte, not at that byte. This code first appeared at: http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=commitdiff;h=cef13d98eb134defcfc125debf38cc6749e153c8 At that time, block[] (now edid[]) pointed at the first byte after the type/length byte. Now that it points at the type/length byte, the offsets need adjustment. Signed-off-by: Stephen Warren <swarren@xxxxxxxxxx> --- This patch to non-Tegra code fixes an issue in code that's only present in non-upstream patches in various of the Android/Tegra branches. This particular patch is against the ChromeOS kernel, so you may need slight fuzz when applying it to the various Android/Tegra branches. drivers/video/fbmon.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/video/fbmon.c b/drivers/video/fbmon.c index 499ce8d..7f6fbf2 100644 --- a/drivers/video/fbmon.c +++ b/drivers/video/fbmon.c @@ -1010,8 +1010,9 @@ void fb_edid_add_monspecs(unsigned char *edid, struct fb_monspecs *specs) } else if (type == 0x3) { if (len >= 3) { - u32 ieee_reg = edid[pos] | (edid[pos+1] << 8) | - (edid[pos+2] << 16); + u32 ieee_reg = edid[pos+1] | + (edid[pos+2] << 8) | + (edid[pos+3] << 16); if (ieee_reg == 0x000c03) specs->misc |= FB_MISC_HDMI; } -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
