Subject: Re: [PATCH v3 2/2] iio: imu: inv_icm42600: switch to use generic name
 irq get

Hello Andy,

I tried to respond inline, but my apologies it is not working well with the email client I'm obliged to use.

To sum-up, property.h is already included and I will simplify the fwnode usage to use the API calls directly.

I will just keep the over 80 limit following Jonathan recommendations.

Thanks,
JB

If you use 100 limit, it fits now on one line.

Ditto.

Do you need to include property.h?

property.h is already included.

Unneeded check, the below will do it for you,

OK, I will simplify and user directly the fwnode functions.

This is now one line (81 characters which is fine independently on your choice
of the limit).

One line.
