Subject: [PATCH 4.8 26/49] Revert "bnx2: Reset device during driver initialization"

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Baoquan He <bhe@...hat.com>


[ Upstream commit 5d0d4b91bf627f14f95167b738d524156c9d440b ]

This reverts commit 3e1be7ad2d38c6bd6aeef96df9bd0a7822f4e51c.

When people build bnx2 driver into kernel, it will fail to detect
and load firmware because firmware is contained in initramfs and
initramfs has not been uncompressed yet during do_initcalls. So
revert commit 3e1be7a and work out a new way in the later patch.
