The patch titled

------------------------------------------------------
Subject: rtc-pcf8583: Don't abuse I2C_M_NOSTART
From: Jean Delvare <[EMAIL PROTECTED]>
The rtc-pcf8583 driver is using the I2C_M_NOSTART flag but shouldn't. This
flag is only meant for broken chips and the PCF8583 RTC chip is not one of
these.
