From: Sai Praneeth <[email protected]> Presently, efi_delete_dummy_variable() uses set_variable() which might block and hence kernel prints stack trace with a warning "bad: scheduling from the idle thread!". So, make efi_delete_dummy_variable() use set_variable_nonblocking(), which, as the name suggests doesn't block.
