# HG changeset patch # User Tim Deegan <Tim.Deegan@xxxxxxxxxx> # Date 1302177332 -3600 # Node ID 44e603c1c0cb9f278138da9dad446fd3493869b7 # Parent d07dbbb17473e8b668415b1db96112eaae9f2e09 Remove "uninitialized_var" macro, which doesn't work with clang. Since its only user is in ACPI parsing code, the extra overhead of initializing to 0 is not worth fighting over.
