Subject: [PATCH net-next 10/11] r8169: simplify ocp functions
Date: Mon, 19 Nov 2018 22:40:04 +0100 [thread overview]
Message-ID: <56b02494-b056-99f2-c018-cf7c67414975@gmail.com> (raw)
In-Reply-To: <7484b166-100b-52b9-1539-22e9199a8a3a@gmail.com>
rtl8168_oob_notify is used in rtl8168dp_driver_start and
rtl8168dp_driver_stop only, so we can rename it to r8168dp_oob_notify.
The same applies to condition rtl_ocp_read_cond which can be renamed
to rtl_dp_ocp_read_cond. This allows to simplify the code.
