From f3307f7276067e2f8f29a20e3ebe52887e8f9f00 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 8 Nov 2007 17:27:47 +0000 Subject: [PATCH] [SCSI] aacraid: don't assign cpu_to_le32(int) to u8 On Wed, Nov 07, 2007 at 01:51:44PM -0500, Salyzyn, Mark wrote: > Christoph Hellwig [mailto:hch@infradead.org] sez: > > Did anyone run the driver through sparse to see if we have > > more issues like this? > > There are some warnings from sparse, none like this one. I will deal > with the warnings ... Actually there are a lot of endianess warnings, fortunately most of them harmless. The patch below fixes all of them up (including the ones in the patch I replied to), except for aac_init_adapter which is really odd and I don't know what to do.
