From 25252919a1050e4e013a40e4c5d2645e677157a0 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 28 Jul 2020 01:11:49 +0800 Subject: [PATCH] xhci: dbgtty: Make some functions static The sparse tool complains as follows: drivers/usb/host/xhci-dbgtty.c:401:5: warning: symbol 'xhci_dbc_tty_register_device' was not declared. Should it be static? drivers/usb/host/xhci-dbgtty.c:452:6: warning: symbol 'xhci_dbc_tty_unregister_device' was not declared. Should it be static? After commit 6ae6470bfa33 ("xhci: dbc: Add a operations structure to access driver functions"), those functions are not used outside of xhci-dbgtty.c, so this commit marks them static.
