From 34eab43ed2483e69bc79fd2e3aaf5adfae771907 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Wed, 4 Jun 2014 09:18:29 +0200 Subject: [PATCH] drm/prime: Use unsigned type for number of pages The number of pages can never be negative, so an unsigned type is enough. This also matches the type of the n_pages argument of the sg_alloc_table_from_pages() function.
