hello Marek,

after applying the patch to dahdi-linux-2.2.1.1

when i run make i got this error.


usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp/base.c:60:2: error: #error
Sorry, wcb4xxp does not support chunksize != 8
make[3]: *** [/usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp/base.o]
Error 1
make[2]: *** [/usr/src/dahdi-linux-2.2.1.1/drivers/dahdi/wcb4xxp] Error 2

Thanks
