Subject: [PATCH] scsi: mvsas: replace kfree with scsi_host_put
References: bsc#1077989
Git-commit: cf99dc30bcc56c33243b5bbfef9d8ea943dd2e1c
Patch-mainline: v4.14-rc1

The return value of scsi_host_alloc() should be released by
scsi_host_put(). However, in function mvs_pci_init(), kfree()
is used. This patch replaces kfree() with scsi_host_put() to avoid
possible memory leaks.
