From 1639664fb74f30eaf82231fccbcf4e34a6e71f7f Mon Sep 17 00:00:00 2001 From: Gil Fine Date: Fri, 17 Dec 2021 03:16:40 +0200 Subject: thunderbolt: Move usb4_switch_wait_for_bit() to switch.c Currently usb4_switch_wait_for_bit() used only in usb4.c Moving to switch.c to call it from other files. Also change the prefix to "tb_" to follow to the naming convention.
