When removing the adt7470 module, a warning might be printed: do not call blocking ops when !TASK_RUNNING; state=1 set at [<ffffffffa006052b>] adt7470_update_thread+0x7b/0x130 [adt7470] This happens because adt7470_update_thread() can leave the kthread in TASK_INTERRUPTIBLE state when the kthread is being stopped before the call of set_current_state(). Since kthread_exit() might sleep in exit_signals(), the warning is printed. Fix that by using schedule_timeout_interruptible() and removing the call of set_current_state(). This causes TASK_INTERRUPTIBLE to be set after kthread_should_stop() which might cause the kthread to exit.

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.
