[PATCH] i2c: i2c-ibm_iic message can be confusing
This is a trivial patch that does not need to be in 2.6.29. While tracking down an EEPROM problem, I found the messages confusing... it looked like the EEPROM was being started before the I2C driver! Here is an example: at24 0-0052: 512 byte 24c04 EEPROM (writable) ibm-iic ef600700.i2c: using standard (100 kHz) mode ad7414 0-004a: chip found It looks like the at24 starts first, then the i2c driver, then the ad7414. By moving the message to after the of scan, we always get the driver, then the devices. Cheers, Sean Print the i2c driver message before scanning for devices so that the logs show the driver, then the devices. Currently you can get device(s), driver, device(s).

No, I'm not taking it, i2c-ibm_iic is under Ben Dooks' jurisdiction. So it's up to either him or you. -- Jean Delvare ___ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev

Ben, Do you want to take this through your tree or should I take it through the powerpc tree? I'll be up-front and say silence will translate to 'powerpc tree' josh > >Cheers, > Sean > >On Mon, 2 Feb 2009 12:01:59 -0500 >Sean MacLennan wrote: > >> This is a trivial patch that does not need to be in 2.6.29.
