From bae7c690354b585d98ae15bd8b1b7b0ba2bb3c42 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 25 May 2016 22:18:15 +0200 Subject: [PATCH] greybus: remove redundant latency-tag sanity checks Core will never call host-device callbacks with invalid arguments (and that would still need to be verified in bridge firmware anyway), so remove the redundant and insufficient sanity check from the callbacks.
