From 9e661cedcc0a072d91a32cb88e0515ea26e35711 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Wed, 12 Feb 2020 10:35:30 +0100 Subject: i2c: jz4780: silence log flood on txabrt The printout for txabrt is way too talkative and is highly annoying with scanning programs like 'i2cdetect'. Reduce it to the minimum, the rest can be gained by I2C core debugging and datasheet information. Also, make it a debug printout, it won't help the regular user.
