media: i2c: Fix pixel array positions in ov8865

[PATCH] media: i2c: Fix pixel array positions in ov8865

Posted by Daniel Scally 4 years, 4 months ago

The ov8865's datasheet gives the pixel array as 3296x2528, and the
active portion as the centre 3264x2448. This makes for a top offset
of 40 and a left offset of 16, not 32 and 80.

Fixes: acd25e220921 ("media: i2c: Add .get_selection() support to ov8865")
