From cf01514c5c6efa2d521d35e68dff2e0674d08e91 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 23 Jan 2020 00:43:06 +0200 Subject: [PATCH] habanalabs: patched cb equals user cb in device memset During device memory memset, the driver allocates and use a CB (command buffer). To reuse existing code, it keeps a pointer to the CB in two variables, user_cb and patched_cb. Therefore, there is no need to "put" both the user_cb and patched_cb, as it will cause an underflow of the refcnt of the CB.
