Subject: [PATCH V2 12/13] pm80xx : Tie the interrupt name to the module instance.
Date: Thu, 14 Nov 2019 15:39:09 +0530	[thread overview]
Message-ID: <20191114100910.6153-13-deepak.ukey@microchip.com> (raw)
In-Reply-To: <20191114100910.6153-1-deepak.ukey@microchip.com>

From: Vikram Auradkar <auradkar@google.com>

With msix enabled, the interrupt instances are <prefix><index> where
the prefix is fixed for all module instances, making it a little
harder to track down what's what.
