why do we need this variable ?
Hi Shashank,
If any error comes while the device is booting then amdgpu will start
unloading everything.
So I am using 'initialized' for unloading a driver successfully. This
variable is to identify that the driver is loaded or not.
This is the below error for which the amdgpu driver is unloading when it
is not getting firmware.
