From 0668db41b5d8a834a04be3b281fa9452dcf3dc18 Mon Sep 17 00:00:00 2001 From: Ilia Levi Date: Mon, 19 Aug 2024 12:13:07 +0300 Subject: [PATCH] accel/habanalabs: remove old interface variation of 'access_ok()' The access_ok() API no longer requires the VERIFY_WRITE argument, and the use of the old interface with VERIFY_WRITE is deprecated. Clean up the habanalabs memory manager to use the modern access_ok() interface consistently. This removes old #ifdef guards and aligns the driver with current upstream kernel APIs.
