Re: [PATCH v9 2/2] media:imx274 V4l2 driver for Sony imx274 CMOS sensor

Hi Vishal, In probe(), it calls imx274_load_default(imx274), which has I2C register read/write to the IMX274. If it fails, it will exit probe(). So it works as a sensor detection function as you suggested. Regards, Leon Luo 1130 Cadillac CT Milpitas, CA 95035 Phone: (510)371-1169 Fax: (408) 217
