The printout for txabrt is way too talkative. 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. Reported-by: H. Nikolaus Schaller <hns@goldelico.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de> --- Sorry, normally I don't do counter patches. Yet, this time I realized that it would be faster to actually do what I envisioned than to describe it in words. I hope you don't feel offended. This driver has way too many dev_err anyhow, so this may be a start. Obviously, I can't test, does it work for you? drivers/i2c/busses/i2c-jz4780.c | 36 ++------------------------------- 1 file changed, 2 insertions(+), 34 deletions(-)
