isx019 driver freezes by I2C access in the interrupt context.
This I2C access is intended to stop data output from FPGA.
Delete this I2C access for the following reasons.
- Data output from FPGA does not affect power consumption
- There are no problems in capture restart without data output stop
since restart is done by image data block first.
When the value that is out of range is specified in ioctl(VIDIOC_S_CTRL) and
ioctl(VIDIOC_S_EXT_CTRLS), returned value should be not EINVAL but ERANGE.
The driver is provided by Spresense SDK
ISX019 has the DOL-HDR feature, which combines images with different exposure so that
both bright and dark data of high-contrast subject can be viewed at the same time.
