From 818a45b1d7fbd8c55a4248fe6cd0995e06db04be Mon Sep 17 00:00:00 2001 From: Nicholas Mc Guire Date: Fri, 13 Mar 2015 07:54:46 -0400 Subject: [PATCH] mtd: fsmc_nand: match wait_for_completion_timeout return type return type of wait_for_completion_timeout is unsigned long not int. An appropriately named unsigned long is added and the assignment fixed up. This not only should help readability but also handles corner cases properly.
