+Subject: [PATCH] media: i2c: imx290: set the format before
+ VIDIOC_SUBDEV_G_FMT is called
+
+Commit d46cfdc86c30d5ec768924f0b1e2683c8d20b671 upstream.
+
+With the current driver 'media-ctl -p' issued right after the imx290 driver
+is loaded prints:
+pad0: Source
+             [fmt:unknown/0x0]
+
+The format value of zero is due to the current_format field of the imx290
+struct not being initialized yet.
+
+As imx290_entity_init_cfg() calls imx290_set_fmt(), the current_mode field
+is also initialized, so the line which set current_mode to a default value
+in driver's probe() function is no longer needed.
