[ Upstream commit131ae388b8] In dvb_usb_i2c_init, if i2c_add_adapter fails, it only prints an error message, and then continues to set DVB_USB_STATE_I2C. This affects the logic of dvb_usb_i2c_exit, which leads to that, the deletion of i2c_adap even if the i2c_add_adapter fails. Fix this by returning at the failure of i2c_add_adapter and then move dvb_usb_i2c_exit out of the error handling code of dvb_usb_i2c_init.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
