From 8d6a9f5676f0e734967ac3739f5c6a28a0b047d9 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Wed, 1 Jul 2015 11:31:27 +0200 Subject: [PATCH] storvsc: use shost_for_each_device() instead of open coding Comment in struct Scsi_Host says that drivers are not supposed to access __devices directly. storvsc_host_scan() doesn't happen in irq context so we can just use shost_for_each_device().
