Subject: cnic: Fix symbol_put_addr() panic on ia64.
X-Git-Tag: firefly_0821_release~13027^2~36
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=64c6460875957502541a4ba30835ac625a0bee79;p=firefly-linux-kernel-4.4.55.git

cnic: Fix symbol_put_addr() panic on ia64.

When the cnic driver tries to grab a symbol from bnx2 when bnx2 is
running init code, symbol_get() will succeed but symbol_put_addr()
will hit BUG() a moment later.  module_text_address() fails because
bnx2 is still in init code.

This is fixed by using symbol_put() instead which does the exact
opposite of symbol_get().
