[net 5/6] bnx2x: handle CHIP_REVISION during init_one

From: Yuval Mintz <hidden>
Date: 2012-01-23 10:37:48
Subsystem: broadcom bnx2x 10 gigabit ethernet driver, networking drivers, the rest · Maintainers: Sudarsana Kalluru, Manish Chopra, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Ariel Elior <redacted>

The macro `CHIP_IS_E1x' requires `bp' to be initialized.
As `bp' is not yet initialized during this phase of `bnx2x_init_dev',
it accessed uninitialized fields in the struct.
