Greg Kroah-Hartman cbce3de28c MHI Host
========
 
 - Fixed the module description
 
 MHI Endpoint
 ============
 
 - Powered down the MHI EP stack completely during MHI RESET instead of just
   doing transfer abort as the MMIO register access will be prohibited
   afterwards. EP stack will also be powered on again in case the RESET
   happened due to SYS_ERR.
 
 - Added a sanity check before processing the command ring to make sure that
   the channel is supported by the controller.
 
 - Added a check to make sure the xfer_cb is available for the channel
   before trying to send the error status to the client drivers. This
   helps in avoiding a potential null pointer dereference.
 
 - Fixed the debug log of RESET command
 
 - Modified the channel ring handler lock to protect the whole handler
   instead of locking it partially. This helps in avoiding a race that may
   happen if a channel STOP/RESET command is issued by the host parallely.
 
 - Saved the MHI state locally during suspend and resume. Otherwise, the MHI
   EP stack will not be aware of a channel that got disabled and may try to
   access it later.
 
 - Changed the MHI state_lock to mutex instead of spinlock. This helps in
   avoiding the sleeping in atomic bug reported by Dan Carpenter and also
   allows the lock to be held throughout the state change.
 
 - Fixed the off by one error while doing the MHI channel check during
   command ring processing.
 
 MHI Generic
 ===========
 
 - Updated the MHI toplevel Makefile to use Kconfig flags for building the
   host and endpoint sub-directories conditionally.
