[dlls\comctl32\listview.c:4222] -> [dlls\comctl32\listview.c:4247]: (warning)
Possible null pointer dereference: lpItem - otherwise it is redundant to check
it 

lpItem may be null but later it's used without check:

 4193     if (infoPtr->dwStyle & LVS_OWNERDATA)
 4194     {
 4195         /* a virtual listview only stores selection and focus */
 4196         if (lpLVItem->mask & ~LVIF_STATE)
 4197             return FALSE;
 4198         lpItem = NULL;
 4199     }

...

 4222     if ((lpLVItem->mask & LVIF_IMAGE) && (lpItem->hdr.iImage !=
lpLVItem->iImage))
 4223         uChanged |= LVIF_IMAGE;
 4224 
 4225     if ((lpLVItem->mask & LVIF_PARAM) && (lpItem->lParam !=
lpLVItem->lParam))
 4226         uChanged |= LVIF_PARAM;
