- Subject: [PATCH] MIPS: ralink: fix clearing the illegal access interrupt
- Due to a typo the illegal access interrupt is never cleared in by
- the interupt handler, causing an effective deadlock on the first
- illegal access.
- This was broken since the code was introduced in 5433acd81e87 ("MIPS:
- ralink: add illegal access driver"), but only exposed when the Kconfig
- symbol was added, thus enabling the code.
- Cc: <stable@vger.kernel.org> [3.18+]
- Fixes: a7b7aad383c ("MIPS: ralink: add missing symbol for RALINK_ILL_ACC")
- Signed-off-by: Jonas Gorski <jogo@openwrt.org>
