Subject: [PATCH 3.18 25/27] can: xilinx_can: fix RX overflow interrupt not being enabled
Date: Fri, 27 Jul 2018 12:27:02 +0200 [thread overview]
Message-ID: <20180727102649.966719982@linuxfoundation.org> (raw)
In-Reply-To: <20180727102649.049641021@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anssi Hannula <anssi.hannula@bitwise.fi>
commit 83997997252f5d3fc7f04abc24a89600c2b504ab upstream.
RX overflow interrupt (RXOFLW) is disabled even though xcan_interrupt()
processes it. This means that an RX overflow interrupt will only be
processed when another interrupt gets asserted (e.g. for RX/TX).
Fix that by enabling the RXOFLW interrupt.
Fixes: b1201e44f50b ("can: xilinx CAN controller support")
