From c4860ad60564838994b74e7ee7dd12ceeda0f520 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Mon, 31 Jul 2017 19:55:08 +0100 Subject: lib/scatterlist: Fix offset type in sg_alloc_table_from_pages Scatterlist entries have an unsigned int for the offset so correct the sg_alloc_table_from_pages function accordingly. Since these are offsets withing a page, unsigned int is wide enough. Also converts callers which were using unsigned long locally with the lower_32_bits annotation to make it explicitly clear what is happening. v2: Use offset_in_page.
