The top-row keys in a keyboard usually have dual functionalities.
E.g. A function key "F1" is also an action key "Browser back".
Therefore, when an application receives an action key code from
a top-row key press, the application needs to know how to correlate
the action key code with the
This patch adds a new property `function-row-physmap` to the
device tree for the custom keyboard top row design.
The property describes the rows/columns of the top row keys
from left to right.

- add `function-row-physmap`
Since commit 1d6cd3929360 ("modpost: turn missing MODULE_LICENSE()

Many drivers don't want interrupts enabled automatically due to
request_irq(). So they are handling this issue by either way of
the below two:
(1)
irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
(2)
request_irq(dev, irq...);
disable_irq(irq);
The code in the second way is silly

mutex lock can be initialized automatically with DEFINE_MUTEX()
rather than explicitly calling mutex_init().
