Subject: mlxbf_gige: stop PHY during open() error paths
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d6c30c5a168f8586b8bcc0d8e42e2456eb05209b;p=linux.git

mlxbf_gige: stop PHY during open() error paths

The mlxbf_gige_open() routine starts the PHY as part of normal
initialization.  The mlxbf_gige_open() routine must stop the
PHY during its error paths.
