Documentation: Fix createRequest unique_ptr
camera->createRequest() function return std::unique_ptr<Request>, then manipulate Request as std::unique_ptr. This solve the following error, during compilation: error: cannot convert ‘std::unique_ptr<libcamera::Request>’ to ‘libcamera::Request*’ in initialization References: - https://github.com/kbingham/simple-cam/blob/bb97f3bbd96a9d347e1b7f6cb68d94efaf8db574/simple-cam.cpp#L369 Signed-off-by: Tommaso Merciai <tommaso.merciai@amarulasolutions.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
