[PATCH 4/4] drivers: staging: remove BUG_ON

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



drivers/staging/android/ion/ion.c calls BUG_ON in places where WARN_ON will
suffice.

This patch replaces two such occurences. Two other occurences remain.

Changing the remaining two BUG_ON's causes changes to the programm logic.

This is my first patch set to the kernel, I am as such, not comfortable
changeing the logic of this file at this early stage of the game. :)
