* Add "no BKL needed" comments to several driversJonathan Corbet2008-06-20
| | | | | | | | This documents the fact that somebody looked at the relevant open() functions and concluded that, due to their trivial nature, no locking was needed. Signed-off-by: Jonathan Corbet <corbet@lwn.net>

| | | | Parts of the serial code actually BUG() if we don't do this.

| * i2c/max6875: Really prevent 24RF08 corruptionJean Delvare2008-05-18
| | | | | | | | | | | | | | | | | | | | | | | | i2c-core takes care of the possible corruption of 24RF08 chips for quite some times, so device devices no longer need to do it. And they really should not, as applying the prevention twice voids it. I thought that I had fixed all drivers long ago but apparently I had missed that one.

| * i2c-amd756: Fix functionality flagsJean Delvare2008-05-18
| | | | | | | | | | | | | | The i2c-amd756 driver pretends to support SMBus process call transactions but actually does not. Fix it. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c: Kill the old driver matching schemeJean Delvare2008-05-18
| | | | | | | | | | | | | | Remove the old driver_name/type scheme for i2c driver matching. Only the standard aliasing model will be used from now on. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c: Convert remaining new-style drivers to use module aliasingJean Delvare2008-05-18
| | | | | | | | | | | | | | | | | | | | | | | | Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c-nforce2: Disable the second SMBus channel on the DFI Lanparty NF4 ExpertJean Delvare2008-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a strange chip at 0x2e on the second SMBus channel of the DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the system. As there's nothing interesting on this SMBus channel, the easiest and safest thing to do is to disable it on that board. This is a better fix to bug #5889 than the it87 driver update that was done originally: http://bugzilla.kernel.org/show_bug.cgi?id=5889 Signed-off-by: Jean Delvare <khali@linux-fr.org>
