[PATCH] habanalabs/gaudi2: added memset for the cq_size register
From: Marco Pagani
Date: Wed Nov 23 2022 - 04:00:34 EST
The clang-analyzer reported a warning: "Value stored to
'cq_size_addr' is never read".
The cq_size register of dcore0 is not being zeroed using
gaudi2_memset_device_lbw(), along with the other cq_* registers,
even though the corresponding cq_size_addr variable is set.
