Subject: [PATCH v7 3/8] can: m_can: Remove check for version when allocating m_can net device
Date: Wed, 10 Jan 2018 16:25:20 +0530	[thread overview]
Message-ID: <1515581725-29242-4-git-send-email-faiz_abbas@ti.com> (raw)
In-Reply-To: <1515581725-29242-1-git-send-email-faiz_abbas@ti.com>

Currently the m_can version is used to set the tx_fifo_count to 1 when
allocating the net device. However, this is redundant as a value of 1
for the tx_fifo_count needs to be provided in the bosch,mram-cfg
property of the device tree node anyway.

Therefore, remove check for version when allocating the net device.
