[PATCH] I2O: Bugfixes to get I2O working again
From: Markus Lidel <Markus.Lidel@shadowconnect.com>
- Fixed locking of struct i2o_exec_wait in Executive-OSM
- Removed LCT Notify in i2o_exec_probe() which caused freeing memory and
accessing freed memory during first enumeration of I2O devices
- Added missing locking in i2o_exec_lct_notify()
- removed put_device() of I2O controller in i2o_iop_remove() which caused
the controller structure get freed to early
- Fixed size of mempool in i2o_iop_alloc()
- Fixed access to freed memory in i2o_msg_get()
