Thanks for the patch. The original code works fine but functions are always by reference, the preference is without &. First patch version is typically 1 and there's no need to denote that.

There are obvious errors for the initializer of ov02a10_i2c_driver, ov2682_i2c_driver, and ov5695_i2c_driver as the code intended to assign "address of function pointer" to function pointer. This patch fixes them by removing redundant & operators.
