If release is part of frontend ops then it is called in the course of dvb_frontend_detach. The process also decrements the module usage count. The problem is if the lgdt3306a driver is reached via i2c_new_device, then when it is eventually destroyed remove is called, which further decrements the module usage count to negative. After this occurs the driver is in a bad state and no longer works. Also fixed by NULLing out the release callback is a double kfree of state, which introduces arbitrary oopses/GPF. This problem is only currently reachable via the em28xx driver.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
