H A D | max2175.c | baf1b186 Thu Oct 19 11:31:21 CDT 2017 Akinobu Mita <akinobu.mita@gmail.com> media: max2175: don't clear V4L2_SUBDEV_FL_IS_I2C
The v4l2_i2c_subdev_init() sets V4L2_SUBDEV_FL_IS_I2C flag in the subdev->flags. But this driver overwrites subdev->flags immediately after calling v4l2_i2c_subdev_init(). So V4L2_SUBDEV_FL_IS_I2C is not set after all.
This stops breaking subdev->flags and preserves V4L2_SUBDEV_FL_IS_I2C.
Side note: According to the comment in v4l2_device_unregister(), this is problematic only if the device is platform bus device. Device tree or ACPI based devices are not affected.
