   And an oops from me: a keen-eyed local correspondent spotted that

Subject: [PATCH] media: adv7604: fix probe of ADV7611/7612

Prior to commit f862f57d ("[media] media: i2c: ADV7604: Migrate to
regmap"), the local variable 'val' contained the combined register
reads used in the chipset version ID test. Restore this expectation
so that the comparison works as it used to.
