[Qemu-devel] [PATCH 5/8] hw/dma/omap_dma: Add (uint32_t) casts when shifting uint16_t by 16 |
Date: |

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.

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.
