Subject: [PATCH 01/14] i2c: jz4780: suppress txabrt reports for i2cdetect
Date: Tue, 11 Feb 2020 22:41:18 +0100 [thread overview]
Message-ID: <7facef52af9cff6ebe26ff321a7fd4f1ac640f74.1581457290.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1581457290.git.hns@goldelico.com>
This suppresses "simple" error reasons
ABRT_7B_ADDR_NOACK
ABRT_10ADDR1_NOACK
ABRT_10ADDR2_NOACK
from flooding the console log when running i2cdetect on
addresses without a responding slave.
Additionally, reading the JZ4780_I2C_TAR in this situation
seems to harm the controller state.
