commit 1091eb830627625dcf79958d99353c2391f41708 upstream.
If a process is interrupted while accessing the radio device and the
core lock is contended, release() could return early and fail to update
the interrupt mask.
Note that the return value of the v4l2 release file operation is
ignored.

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.
