Subject: [Qemu-devel] [PATCH 5/8] hw/dma/omap_dma: Add (uint32_t) casts when shifting uint16_t by 16
Date: Thu,  8 May 2014 19:46:55 +0100	[thread overview]
Message-ID: <1399574818-19349-6-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1399574818-19349-1-git-send-email-peter.maydell@linaro.org>

Add missing (uint32_t) casts in cases where we're trying to
put a uint16_t value into the top half of a 32-bit field.
These were already present in some but not all places.

Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

For new code or code I cared about I'd use deposit32(); but omap
is pretty ancient and unloved, so this is the minimal fix.
