From 7264892648bac9c1a5f20505a569abf85370b7c4 Mon Sep 17 00:00:00 2001 From: Andrey Smirnov Date: Tue, 18 Jun 2019 22:27:13 -0700 Subject: drm/bridge: tc358767: Simplify tc_aux_wait_busy() We never pass anything but 100 as timeout_ms to tc_aux_wait_busy(), so we may as well hardcode that value and simplify function's signature.
