Interrupt context can't sleep. Drivers like Panfrost and MSM are taking mutex when job is released, and thus, that code can sleep. This results into "BUG: scheduling while atomic" if locks are contented while job is freed. There is no good reason for releasing scheduler's jobs in IRQ context, hence use normal context to fix the trouble.

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.
