Subject: [PATCH] media: imx-jpeg: Disable some unused interrupt
Date: Fri, 27 May 2022 15:54:34 +0800 [thread overview]
Message-ID: <20220527075437.16882-2-ming.qian@nxp.com> (raw)
In-Reply-To: <20220527075437.16882-1-ming.qian@nxp.com>
The interrupt STMBUF_HALF may be triggered after frame done.
It may led to system hang if driver try to access the register after
power off.
And interrupt STMBUF_HALF and STMBUF_RTND have no other effect.
So disable them and the unused interrupts.
