From de5d35aff5b34bc91a83adb0bf1788d3d23e92f4 Mon Sep 17 00:00:00 2001 From: Uma Krishnan Date: Fri, 11 May 2018 14:06:05 -0500 Subject: scsi: cxlflash: Abstract hardware dependent assignments As a staging cleanup to support transport specific builds of the cxlflash module, relocate device dependent assignments to header files. This will avoid littering the core driver with conditional compilation logic. Signed-off-by: Uma Krishnan Acked-by: Matthew R. Ochs Signed-off-by: Martin K.
