Subject: i40e: Remove EMPR traces from debugfs facility
Patch-mainline: v5.4-rc1
Git-commit: c19d034b54fa9c4beb543768503343a66f6223bc
References: jsc#SLE-8025
Since commit
'5098850c9b9b ("i40e/i40evf: i40e_register.h updates")'
it is no longer possible to trigger an EMP Reset from debugfs, but it's
possible to request it either way, to end up with a bad reset request:
echo empr > /sys/kernel/debug/i40e/0002\:01\:00.1/command
i40e 0002:01:00.1: debugfs: forcing EMPR
i40e 0002:01:00.1: bad reset request 0x00010000
So let's remove this piece of code and show the available valid commands
as it is when any invalid command is issued.
