From a48221a26e4914b7e2d8a1749b6115212bac8bee Mon Sep 17 00:00:00 2001 From: Roland Stigge Date: Tue, 16 Oct 2012 15:24:01 +0200 Subject: [PATCH] gpio-74x164: Fix buffer allocation size The new registers handling in the gpio-74x164 driver allocates chip->registers * 8 bytes where only one byte per register is necessary. This patch fixes this.
