2007-06-01cfag12864bfb: Use sys_ instead of cfb_ framebuffer accessorsAvuton Olrich
Because the framebuffer memory is allocated system RAM, use the sys_ drawing libraries. It also fixes the following compile error: LD .tmp_vmlinux1 drivers/built-in.o:(.data+0x8b48): undefined reference to `cfb_fillrect' drivers/built-in.o:(.data+0x8b50): undefined reference to `cfb_copyarea' drivers/built-in.o:(.data+0x8b58): undefined reference to `cfb_imageblit' [adaplas] Use fb_sys_read/write for the same reasons as above.

2007-02-20[PATCH] cfag12864b: fix crash when built-in and no parport presentMiguel Ojeda
The problem comes when ks0108/cfag12864b are built-in and no parallel port is present. ks0108_init() is called first, as it should be, but fails to load (as there is no parallel port to use). After that, cfag12864b_init() gets called, without knowing anything about ks0108 failed, and calls ks0108_writecontrol(), which dereferences an uninitialized pointer. Init order is OK, I think. The problem is how to stop cfag12864b_init() being called if ks0108 failed to load. modprobe does it for us, but, how when built-in?
