[PATCH net-next 7/7] net: ipa: three small fixes

From: Alex Elder
Date: Fri Apr 09 2021 - 14:07:48 EST


Some time ago changes were made to stop referring to clearing the
hardware pipeline as a "tag process." Fix a comment to use the
newer terminology.

Get rid of a pointless double-negation of the Boolean toward_ipa
flag in ipa_endpoint_config().

make ipa_endpoint_exit_one() private; it's only referenced inside
"ipa_endpoint.c".
