From abd39c6ded9db53aa44c2540092bdd5fb6590fa8 Mon Sep 17 00:00:00 2001 From: Sanjay Konduri Date: Tue, 15 May 2018 14:34:30 +0530 Subject: [PATCH] rsi: add fix for crash during assertions Observed crash in some scenarios when assertion has occurred, this is because hw structure is freed and is tried to get accessed in some functions where null check is already present. So, avoided the crash by making the hw to NULL after freeing.
