From: Jacek Bułatek <jacekx.bulatek@xxxxxxxxx>
commit 7a91d3f02b04b2fb18c2dfa8b6c4e5a40a2753f5 upstream.
Add handling of allocation fault for ice_vsi_list_map_info.
Also *fi should not be NULL pointer, it is a reference to raw
data field, so remove this variable and use the reference
directly.
Fixes: 9daf8208dd4d ("ice: Add support for switch filter programming")
