From 42a84c09eff355d895723866b1a5ff48f093112a Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Thu, 30 Jun 2022 17:32:19 +0200 Subject: vdpa_sim_blk: use dev_dbg() to print errors Use dev_dbg() instead of dev_err()/dev_warn() to avoid flooding the host with prints, when the guest driver is misbehaving. In this way, prints can be dynamically enabled when the vDPA block simulator is used to validate a driver.
