2.6.28-stable review patch. If anyone has any objections, please let us know. ------------------ From: Johannes Berg commit c91276592695e13d1b52eab572551017cbf96ee7 upstream This fixes the checksum calculation for lm87 firmwares on big endian platforms, the device treats the data as an array of 32-bit little endian values so the driver needs to do that as well.
