From eec86b8e85309a2cb0b33bcb361c67d81ebed474 Mon Sep 17 00:00:00 2001 From: Alexander Usyskin <alexander.usyskin@intel.com> Date: Thu, 17 Oct 2013 17:20:22 +0300 Subject: mei: move host_clients_map cleanup to device init Move host_clients_map cleanup from host client init to device init. This fixes bug where we cleaned up the bitmask that servers as pool for host client ids while file descriptors are kept open during suspend. On resume a new connection will be assigned id that is already taken by opened file descriptor. Consequently read/write will fail due to mismatched book keeping.
