Hi all, i have a bf527 custom board with a smart LCD. I m using 2009R1_RC7 distribution.  I m trying to write a framebuffer driver for this LCD in linux-2.6.x/drivers/video folder. i took bfin-t350mcqb-fb.c as reference. I edited the Makefile and Kconfig in video folder and selected the option for my driver  in menu.  During board bootup, i could see driver init function is happening(through printk()). But probe() and other functions not called. So, I could not open /dev/fb0.

But if i edited the same file bfin-t350mcqb-fb.c for our LCD with the same changes as in my custom driver file except DRIVER_NAME macro and selected this option in menu,  everything is successful and i was able to open /dev/fb0. But here also, if i edited the DRIVER_NAME previous problem occurs. I m wondering why this is happening? Do I miss anything? Kindly suggest.
