Shared memory is initialized by CRM and used by other drivers; with CRM not active other drivers would fail to access the shared memory if memory manager is deinit. Reader Writer locks can prevent the open/close/ioctl calls from other drivers if CRM open/close is already being processed. Issue observed with the below sequence if drivers are opened from UMD directly without this change. CRM Open successful,ICP open successful, CRM close in progress, ICP open successful, mem mgr deinit and CRM close successful, ICP tries to access HFI memory and result in crash. This change helps to serialze the calls and prevents issue. CRs-Fixed: 3019488 Change-Id: Ifdf198c2e3593050573c66aeba69d50d131435b9 Signed-off-by: Tejas Prajapati <quic_tpraja@quicinc.com>
