Linux kernel source tree
5abda7a166
In dm1105_probe, it called dm1105_ir_init and bound
&dm1105->ir.work with dm1105_emit_key.
When it handles IRQ request with dm1105_irq,
it may call schedule_work to start the work.
When we call dm1105_remove to remove the driver, there
may be a sequence as follows:
Fix it by finishing the work before cleanup in dm1105_remove
CPU0 CPU1
|dm1105_emit_key
dm1105_remove |
dm1105_ir_exit |
rc_unregister_device |
rc_free_device |
rc_dev_release |
kfree(dev); |
|
| rc_keydown
| //use

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.
