From ed022e5dd3a044b95a68d685d2d2871ce31351df Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Wed, 30 Sep 2020 01:18:47 +0300 Subject: i2c: tegra: Mask interrupt in tegra_i2c_issue_bus_clear() The tegra_i2c_issue_bus_clear() may fail and in this case BUS_CLR_DONE stays unmasked. Hence let's mask it for consistency. This patch doesn't fix any known problems.
