Subject: tg3: negate USE_PHYLIB flag check
X-Git-Tag: firefly_0821_release~3680^2~4349^2~9
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e730c82347b9dc75914da998c44c3f348965db41;p=firefly-linux-kernel-4.4.55.git

tg3: negate USE_PHYLIB flag check

USE_PHYLIB flag in tg3_remove_one() is being checked incorrectly. This
results tg3_phy_fini->phy_disconnect is never called and when tg3 module
is removed.

In my case this resulted in panics in phy_state_machine calling function
phydev->adjust_link.

So correct this check.
