RE: [char-misc-next] mei: hbm: fix client dma reply status

From: Alexander Usyskin alexander.usyskin@intel.com

Don't blindly copy status value received from the firmware into internal client status field, It may be positive and ERR_PTR(ret) will translate it into an invalid address and the caller will crash.

Put the error code into the client status on failure.
