linux 2.6.38 multimedia

enoregrattoni
I use successfully jpeg decoder in linux 2.6.28.6 in mini6410 but when I
use same program in linux 2.6.38 with gcc toolchain 4.5.1 jpeg decoder
fail.
I cannot see the differences between multimedia sources after 2.6.28.6 so I
feel there is no differences.
I use jpgapi.c from multimedia 2.7 example that I found in 2.6.28.6
distribution. 
My idea is that there is some differences necessary in this module.
I hope in some help.
Thanks
