Subject: [PATCH 7/7] staging: fsl-mc: allow the driver compile multi-arch

From: [email-masked] (Laurentiu Tudor)
Date: Thu, 20 Jul 2017 13:47:27 +0000

Hi,

Sparc seems to be broken in multiple places, including generic code.
Is this a known issue?
Is there something I could/should do?

Thanks & Best Regards, Laurentiu
