There is also a reference in ena driver, again, not sure what the correct
code replacement is - setting the struct initializer to {0} perhaps? Adding
some ena maintainers on CC so they can comment on this.
struct ena_com_create_io_ctx ctx =
/* policy set to _HOST just to satisfy icc compiler */
{ ENA_ADMIN_PLACEMENT_POLICY_HOST,
0, 0, 0, 0, 0 };
Ena maintainers - any suggestions on what the code should look like if we
no longer have to support the icc compiler?
