commit20ea39ef9fupstream. The trialmask is expected to have all bits set to 0 after allocation. Currently kmalloc_array() is used which does not zero the memory and so random bits are set. This results in random channels being enabled when they shouldn't. Replace kmalloc_array() with kcalloc() which has the same interface but zeros the memory. Note the fix is actually required earlier than the below fixes tag, but will require a manual backport due to move from kmalloc to kmalloc_array.

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.
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.
