2 issues in /usr/libexec/elogind/system-sleep/nvidia.sh

The nvidia package supplies some shell scripts to help with putting the device into sleep mode.

case "$1" in
   pre)
       logger -t nvidia-sleep "Entering $2 mode (invoked by $SYSTEMD_SLEEP_ACTION)"
       /usr/bin/nvidia-sleep.sh "hibernate"
       ret=$?
       if [ $ret -ne 0 ]; then
               logger -t nvidia-sleep "Failed to enter $2 mode (exit code $ret)"
               exit $ret
       fi
       sleep 5
       logger -t nvidia-sleep "Entered $2 mode (invoked by $SYSTEMD_SLEEP_ACTION)"
       ;;

First, the script ignores the argument completely and always passes hibernate, when it could accept suspend via "$2" as well. I'm not sure if it causes issues, but it looks wrong.
Second thing, the unnecessary sleep for 5 seconds slowing the whole thing down for no reason whatsoever. I just removed that line and nothing broke. ZZZ hook doesn't have the wait time, so I don't think it's doing anything, plus it returns if we succeeded anyway.

Start by reading /usr/libexec/elogind/system-sleep/nvidia.sh and compare its sleep hook with the ZZZ hook mentioned in the issue. Confirm how the pre-action argument is passed and whether the five-second wait is needed; done means the hook handles the requested sleep mode and no longer adds the unnecessary delay.
