Subject: [TG3]: Add missing unlock in tg3_open() error path.
X-Git-Tag: v2.6.19~56^2
X-Git-Url: http://git.rot13.org/?a=commitdiff_plain;h=12862086f24d7382b24379bbcbe0dadf12ca5945;hp=f2776ff047229c3e7cee2454e2704dd6f98fa32f;p=powerpc.git

[TG3]: Add missing unlock in tg3_open() error path.

Sparse noticed a locking imbalance in tg3_open(). This patch adds an
unlock to one of the error paths, so that tg3_open() always exits
without the lock held.
