As Vinod suggested, you may change the commit message to emphasize
that the bug comes from the fact that a single variable is used to store
different information.
The Fixes: tag should be added too.

Hi,
This patchset adds support for the ISO7816 standard. The USART devices
in Microchip SoCs have an ISO7816 mode. It allows to let the USART

Changes:
- v5
- rebase on tty-next.
- add documentation for the new ioctls (mimic rs485 one).
- fix

Sharing the same irqchip with multiple gpiochips is not a good
practice. For instance, when installing hooks, we change the state
of the irqchip. The initial state of the irqchip for the second
gpiochip to register is then disrupted.

Hi,
This fix depends on the support of the drive-strength for the atmel pio4
pinctroller. It has been added in v4.19 but I omitted to send it at the
same time.
