From 8f5c335e34b5ae2dda6db2af300381fc9fb53fe7 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Mon, 4 Oct 2021 14:59:33 +0200 Subject: crypto: qat - simplify adf_enable_aer() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A struct pci_driver is shared across all device instances, so assigning pci_driver.err_handler once per device isn't really sensible. Set adf_driver.err_handler statically instead of in adf_enable_aer(). This removes a use of pci_dev->driver, which is a step toward removing pci_dev->driver altogether. Since adf_enable_aer() returns zero unconditionally, make it a void function.
