From ac9e2d9afa90ecb7ee1b419cce6969f31a138f77 Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Wed, 21 Dec 2011 22:36:28 +0200 Subject: [PATCH] wl1251: convert 32-bit values to le32 before writing to the chip The 32-bit values were not converted before writing them to the chip. Change the wl1251_read32() and wl1251_write32() so that they always read and write le32 values and convert to and from the CPU endianess.
