From 0821ff8ed059d38dfc9bec2106c5cc53bcaa15b1 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Sat, 11 Mar 2023 15:40:09 +0100 Subject: PCI/DOE: Make asynchronous API private A synchronous API for DOE has just been introduced. CXL (the only in-tree DOE user so far) was converted to use it instead of the asynchronous API. Consequently, pci_doe_submit_task() as well as the pci_doe_task struct are only used internally, so make them private.
