From: Shinya Kuribayashi Date: Mon, 16 Nov 2009 11:40:14 +0000 (+0900) Subject: i2c-designware: i2c_dw_handle_tx_abort: Use dev_dbg() for NOACK cases X-Git-Tag: v2.6.33-rc1~339^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d1ea0f6afde6887d6dea2ace1714a23d9b5820d;p=profile%2Fcommon%2Fkernel-common.git i2c-designware: i2c_dw_handle_tx_abort: Use dev_dbg() for NOACK cases In the case of no-ACKs, we don't want to see dev_err() messages in the console, because some utilities like i2c-tools are capable of printing decorated console output. This patch will ease such situations.
