From 67f08d690aa90e47a0e793fc63e2ecbe95d29839 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 1 Aug 2014 17:43:03 +0100 Subject: [PATCH] spi/atmel: Fix pointer to int conversion warnings on 64 bit builds On 64 bit systems integers are generally still 32 bit but long values and pointers are usually 64 bit. GCC warns when casting a 64 bit pointer into a 32 bit integer so cast to a long instead in order to avoid warnings.
