H A D | ks0108.h | diff 34173a4aad7a641e72b70f9927ca797746fbce69 Tue Feb 20 22:58:00 CET 2007 Miguel Ojeda <maxextreme@gmail.com> [PATCH] cfag12864b: fix crash when built-in and no parport present
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?
