I'm getting this errors when I'm compiling the kernel for the DM368, but I have not made any changes on the mt9p031.c file, I had made changes on other files like but why I'm getting errors on this one?

    I would guess you used "Enable advanced debug functionality" in the video portion of the kernel config. That set the CONFIG_VIDEO_ADV_DEBUG flag and causes the problem code to be pulled in. Looks someone at TI did not test compile with this flag on for this version of the kernel. The field names should be "g_register" and "s_register" instead of "get_register" and "set_register". I'd call this bug. For now, you could try changing the field names in mt9p031.c.

    Hi, thanks for the advice, was just some configurations in the kernel I miss, nothing wrong with the code, but the image comes a bit over expose, I try to do some changes on the driver but that didnt work, any ideas where I should be looking at?
