-Subject: [PATCH] media: i2c: ov9281: Read chip ID via 2 reads
-
-Vision Components have made an OV9281 module which blocks reading
-back the majority of registers to comply with NDAs, and in doing
-so doesn't allow auto-increment register reading as used when
-reading the chip ID.
-
-Use two reads and manually combine the results.
