From 7258416c517c79b2ebb30b61d8c6807a04dc6b25 Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Thu, 20 Jun 2013 23:03:12 -0400 Subject: [PATCH] cw1200: Fix up a large pile of sparse warnings Most of these relate to endianness problems, and are purely cosmetic. But a couple of them were legit -- listen interval parsing and some of the rate selection code would malfunction on BE systems. There's still one cosmetic warning remaining, in the (admittedly) ugly code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI transfers, but many SPI controllers only operate 8 bits at a time. If there's a cleaner way of handling this, I'm all ears.
