Subject: isci: Add protocol indicator for TMF requests.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28de92bef0fb0c3953aa73d31a961422ef900e6a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

isci: Add protocol indicator for TMF requests.

Requests contructed as task management requests need to have the protocol
indicator set so the completion decode can observe any RNC suspension
conditions.
