[libcamera-devel] [PATCH 3/6] android: jpeg: exif: Fix setOrientation EXIF values

[Paul Elder]

The input to setOrientation is angle clockwise from 12 o'clock, while
the EXIF output values were swapped for 90 and 270 degrees.

>From the EXIF spec:

6 = The 0th row is the visual right-hand side of the image, and the
    0th column is the visual top.
8 = The 0th row is the visual left-hand side of the image, and the
    0th column is the visual bottom.

6 should be 90 degrees clockwise, while 8 should 270 degrees clockwise.
Fix this.
