From 295938406cbcb541de8893d0280a2265c41e506d Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 4 Apr 2019 14:33:34 +0300 Subject: [PATCH] habanalabs: ASIC_AUTO_DETECT enum value is redundant This patch removes the enum value of ASIC_AUTO_DETECT because we can use the validity of the pdev variable to know whether we have a real device or a simulator. For a real device, we detect the asic type from the device ID while for a simulator, the simulator code calls create_hdev() with the specified ASIC type. Set ASIC_INVALID as the first option in the enum to make sure that no other enum value will receive the value 0 (which indicates a non-existing entry in the simulator array).
