Subject: [PATCH 1/3] platform/x86: intel_scu_ipc: Fix busy loop expiry time
Date:   Tue, 28 Sep 2021 03:19:30 -0700

The macro IPC_TIMEOUT is already in jiffies (it is also used like that
elsewhere in the file when calling wait_for_completion_timeout()). Don’t
convert it using helper functions for the purposes of calculating the
busy loop expiry time.
