Chandrakanth patil 243c4833f3 scsi: megaraid_sas: Increase register read retry rount from 3 to 30 for selected registers ... commit 8e3ed9e786 upstream. In BMC environments with concurrent access to multiple registers, certain registers occasionally yield a value of 0 even after 3 retries due to hardware errata. As a fix, we have extended the retry count from 3 to 30. The same errata applies to the mpt3sas driver, and a similar patch has been accepted. Please find more details in the mpt3sas patch reference link.
