I have some issues with v4l2 on this kernel version and I am trying to upgrade v4l2 to fix that. One last question: Can I remove current v4l codes in kernel, replace them with the V4L2 backport (provided by linuxtv), fix the compatibility issues (hopefully) to get a kernel source with newer v4l2 code? I am not sure if the v4l2 backport is the same type of code that is present in kernel source at "drivers/media/video", "drivers/media/dvb", etc. Thanks, Isaac > Regards, > > Hans > >> >> To bypass this error, I manually added these two includes to >> v4l2-.fh.h file (I guess this is not a good approach): >> >> #include <linux/module.h> >> #include <linux/export.h> >> >> Now when I run make, I get different errors.
