From: Prashant Malani <pmalani@chromium.org>
commit 41512e4dc0b84525495e784295092592adb87f1b upstream.
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.
