Hello Sasikumar Chandrasekaran,
The patch d889344e4e59: "scsi: megaraid_sas: Dynamic Raid Map Changes
for SAS3.5 Generic Megaraid Controllers" from Jan 10, 2017, leads to
the following static checker warning:
drivers/scsi/megaraid/megaraid_sas_fusion.c:2043 megasas_build_ldio_fusion()
warn: curly braces intended?

Wow... You guys are probably already discussed this code, but I'm not
