From 52c74d17d89c6e69f9b774cdd477517e62383f55 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 3 Mar 2022 17:42:56 +0100 Subject: [PATCH] i2c: i801: Drop two outdated comments * Timeouts are reported even in interrupt mode since commit b3b8df97723d ("i2c: i801: Use wait_event_timeout to wait for interrupts") so drop the comment which claims this only happens in polled mode. * xact does not include the PEC bit, as the driver does not support software PEC.
