2009-08-22[SCSI] ses: add support for enclosure component hot removalJames Bottomley
Right at the moment, hot removal of a device within an enclosure does nothing (because the intf_remove only copes with enclosure removal not with component removal). Fix this by adding a function to remove the component.

2009-08-22[SCSI] ses: fix hotplug with multiple devices and expandersJames Bottomley
In a situation either with expanders or with multiple enclosure devices, hot add doesn't always work. This is because we try to find a single enclosure device attached to the host. Fix this by looping over all enclosure devices attached to the host and also by making the find loop recognise that the enclosure devices may be expander remote (i.e. not parented by the host).

2009-07-29eeprom/at25: bugfix "not ready" timeout after writeSebastian Heutling
Under certain circumstances msleep(1) within the loop, which waits for the EEPROM to be finished, might take longer than the timeout. On the next loop the status register might now return to be ready and therefore the loop finishes. The following check now tests if a timeout occurred and if so returns an error although the device reported it was ready. This fix replaces testing the occurrence of the timeout by testing the "not ready" bit in the status register.

Fix potential SGI GRU bug that could cause a use-after-free. If one thread in a task is flushing the GRU and another thread destroys the GRU context, there is the potential to access a table after it has been freed.
