Subject: [PATCH net-next v3 1/3] net: macb: Update gem PTP support check
Date: Mon, 27 Mar 2023 16:36:05 +0530 [thread overview]
Message-ID: <20230327110607.21964-2-harini.katakam@amd.com> (raw)
In-Reply-To: <20230327110607.21964-1-harini.katakam@amd.com>
There are currently two checks for PTP functionality - one on GEM
capability and another on the kernel config option. Combine them
into a single function as there's no use case where gem_has_ptp is
TRUE and MACB_USE_HWSTAMP is false.
