Subject: [PATCH 3/5] Bluetooth: qca: drop bogus edl header checks
Date: Wed,  1 May 2024 14:34:54 +0200	[thread overview]
Message-ID: <20240501123456.6712-4-johan+linaro@kernel.org> (raw)
In-Reply-To: <20240501123456.6712-1-johan+linaro@kernel.org>

The skb->data pointer is never NULL so drop the bogus sanity checks when
initialising the EDL header pointer.
