[PATCH 5/6] habanalabs: print warning when reset is requested

From: Oded Gabbay
Date: Sat Mar 28 2020 - 04:52:56 EST


When the system administrator asks the driver to soft or hard reset the
device through sysfs, the driver should display a warning in the kernel log
to explain why it suddenly resets the device.
