[RFC,PATCH] i2c: fix device_init_wakeup place

[Marc Pignat]

Move device_init_wakeup. At it's current place this is a noop (will be reset in
device_initialize).

Hi all!

The current code calls device_init_wakeup() before device_register, but
device_register will disable device wakeup.

This patch (against 2.6.27-rc1) move the device_init_wakeup() call in the bus
probe function,just before the probe call.

This will fix 3bbb835d4c53faf0bca62f0e39835926bef40b1f ('New style devices can
support driver modle wakeup flags')which in fact has no effect. I think there
is no need to fix -stable, because there is no in-tree users of the
I2C_CLIENT_WAKE flag.

This patch also include a small functionnal change: the I2C_CLIENT_WAKE is no
more removed from the client flags, but this should't hurt.


Best regards

Marc
