From 68b8819daf8e7bee3b3ae504989000a29bef25ec Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Mon, 8 Jul 2019 14:53:43 +0300 Subject: [PATCH] habanalabs: remove write_open_cnt property This property has attempted to show the number of open file descriptors on the device. This was a stupid and futile attempt so remove this property completely.
