[PATCH 02/12] staging: unisys: visorbus: Use switch statement instead of conditionals

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

 



From: David Binder <david.binder@xxxxxxxxxx>

Control flow is now directed using a switch statement, triggered by the
enum crash_obj_type function parameter, instead of a set of conditional
statements.
