Commit Message

Sundaresan, Sujaritha Sept. 8, 2017, 9:47 p.m. UTC 
We currently have two module parameters that control GuC: "enable_guc_loading" and "enable_guc_submission".
Whenever we need i915.enable_guc_submission=1, we also need enable_guc_loading=1.
We also need enable_guc_loading=1 when we want to verify the HuC, which is every time we have a HuC (but all platforms with HuC have a GuC and viceversa).

v2: Unify seq_puts messages, correcting inconsistencies (Michal)
v2: Clarifying the commit message (Anusha)
