* [PATCH] I2C: m41t00: fix incorrect kfreeJean Delvare2005-07-11
| | | | | | | | | | Here is a simple path fixing an incorrect kfree in the m41t00 i2c chip driver. The current code happens to work by accident, but the freed pointer isn't the one which was allocated in the first place, which could cause problems later.

* [PATCH] I2C: New max6875 driver may corrupt EEPROMsJean Delvare2005-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a careful code analysis on the new max6875 driver (drivers/i2c/chips/max6875.c), I have come to the conclusion that this driver may cause EEPROM corruptions if used on random systems. The EEPROM part of the MAX6875 chip is accessed using rather uncommon I2C sequences. What is seen by the MAX6875 as reads can be seen by a standard EEPROM (24C02) as writes. If you check the detection method used by the driver, you'll find that the first SMBus command it will send on the bus is i2c_smbus_write_byte_data(client, 0x80, 0x40). For the MAX6875 it makes an internal pointer point to a specific offset of the EEPROM waiting for a subsequent read command, so it's not an actual data write operation, but for a standard EEPROM, this instead means writing value 0x40 to offset 0x80. Blame Philips and Intel for the obscure protocol. Since the MAX6875 and the standard, common 24C02 EEPROMs share two I2C addresses (0x50 and 0x52), loading the max6875 driver on a system with standard EEPROMs at either address will trigger a write on these EEPROMs, which will lead to their corruption if they happen not to be write protected. This kind of EEPROMs can be found on memory modules (SPD), ethernet adapters (MAC address), laptops (proprietary data) and displays (EDID/DDC). Most of these are hopefully write-protected, but not all of them. For this reason, I would recommend that the max6875 driver be neutralized, in a way that nobody can corrupt his/her EEPROMs by just loading the driver. This means either deleting the driver completely, or not listing any default address for it. I'd like this to be done before 2.6.13-rc1 is released. Additionally, the max6875 driver lacks the 24RF08 corruption preventer present in the eeprom driver, which means that loading this driver in a system with such a chip would corrupt it as well. Here is a proposed quick patch addressing the issue, although I wouldn't mind a complete removal if it makes everyone feel safer. I think Ben has plans to replace this driver by a much simplified one anyway. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| * | [MTD] NAND: Reorganize chip lockingThomas Gleixner2005-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
