bnx2: Pre-initialize struct cpu_reg.
Browse files Browse the repository at this point in the history 
Instead of assigning values for the struct cpu_reg's at runtime,
we already know these values at compile time.  Therefore, we can use
designated initializers, to initialize these structures and not have
to incur this assignment cost at run-time.
