[libcamera-devel] [PATCH 4/4] android: jpeg: exif: change GPS method from UNDEFINED format to ASCII

[Paul Elder]

According to the EXIF specification, the GPS method should be UNDEFINED,
and the first 8 bytes will designate the type. However, CTS expects the
GPS method to be ASCII. Change the format to ASCII to appease CTS.

This is part of the fix that allows the following CTS test to pass:
- android.hardware.cts.CameraTest#testJpegExif
