Subject: [PATCH iwl-net] ice: fix DDP package download for packages without signature segment
From: Dan Nowlin <dan.nowlin@...el.com>
Commit 3cbdb0343022 ("ice: Add support for E830 DDP package segment")
incorrectly removed support for package download for packages without a
signature segment. These packages include the signature buffer inline
in the configurations buffers, and do not in a signature segment.
Fix package download by providing download support for both packages
with (ice_download_pkg_with_sig_seg()) and without signature segment
(ice_download_pkg_without_sig_seg()).
Fixes: 3cbdb0343022 ("ice: Add support for E830 DDP package segment")
