From 84281c2d72a70456a3ba8d1e49548dd469f2e9d8 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Fri, 12 Aug 2016 14:46:14 +0200 Subject: [PATCH] rtc: sysfs: fix a cast removing the const attribute The char pointer buf_ptr is assigned an address from a const char pointer buf (parameter of wakealarm_store). The data pointer by buf_ptr is never modified. So casting it to a (char *) is useless. This patch remove this cast, and transform buf_ptr to a const char pointer.
