Hi Greg,

After merging the tty tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/mfd/at91-usart.c:51:34: error: array type has incomplete element type 'struct of_device_id'

Caused by commit

   7d3aa342cef7 ("mfd: at91-usart: Add MFD driver for USART")

Forgot to include <linux/mod_devicetable.h>?

Looks like a missing Device Tree header <linux/of.h>.

Will chase this today and follow up with another PR.

Hi all,

Actually it is due to the missing of <linux/mod_devicetable.h> as Stephen suggested. It is due to the patch ac3167257b9f ("headers: separate linux/mod_devicetable.h from linux/platform_device.h") merged in v4.19-rc1.

because linux/platform_device.h was included by linux/mfd/core.h that is present in this driver. This is why the issue was not identified beforehand.

I'm building a tiny patch to address this right now.

Thanks for your help. Best regards,
