From 5c64efd81ffa33eefb75c1215b73e0f329a67e55 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 11 Aug 2020 16:39:35 +0300 Subject: scsi: ufs: Fix interrupt error message for shared interrupts [ Upstream commit 6337f58cec030b34ced435b3d9d7d29d63c96e36 ] The interrupt might be shared, in which case it is not an error for the interrupt handler to be called when the interrupt status is zero, so don't print the message unless there was enabled interrupt status.
