Subject: mei: me: fix waiting for hw ready
From: Tomas Winkler <[email protected]>
commit dab9bf41b23fe700c4a74133e41eb6a21706031e upstream.
1. MEI_INTEROP_TIMEOUT is in seconds not in jiffies
so we use mei_secs_to_jiffies macro
While cold boot is fast this is relevant in resume
2. wait_event_interruptible_timeout can return with
-ERESTARTSYS so do not override it with -ETIMEDOUT
3.Adjust error message
