It'll be about the same number of lines, too.

To distinguish ov9281 & ov9282 the name has to be explicitly set. i2c_client already has the name parsed from the compatible. Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com> --- drivers/media/i2c/ov9282.c | 1 + 1 file changed, 1 insertion(+)
