[PATCH v1 2/2] media: imx: imx8mq-mipi-csi2: remove wrong irq config write operation
From: Martin Kepplinger <hidden>

Also in:
linux-arm-kernel, linux-media, lkml
Subsystem:
media drivers for freescale imx, media input infrastructure (v4l/dvb), staging subsystem, the rest · Maintainers:
Steve Longerbeam, Philipp Zabel, Mauro Carvalho Chehab, Greg Kroah-Hartman, Linus Torvalds
The place where this register writel() that masks one interrupt is placed
does not guarantee that the device is powered so that's not allowed. Moreover
imx8mq_mipi_csi_start_stream() masks the interrupt anyway so the
write is not even needed. Remove it as this is a mistake that slipped in
with the driver.
Fixes: f33fd8d77dd0 ("media: imx: add a driver for i.MX8MQ mipi csi rx phy and controller")
