Reading from this file -displays what the current detach state is set to. This is 0 (On) by -default. A user may write a positive integer value to this file in the -range of 1-4 inclusive. - -A value of 1-3 will indicate the device should be placed in that -low-power state, which will cause ->suspend() to be called for that -device. A value of 4 indicates that the device should be shutdown, so -->shutdown() will be called for that device. - -The driver is responsible for reinitializing the device when the -module is re-inserted during it's ->probe() (or equivalent) method. -The driver core will not call any extra functions when binding the -device to the driver. pm_message_t meaning |
