Subject: [PATCH] common: bouncebuf: Add missing cast to dma_addr_t
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
Fix the following warning produced on qemu-x86_64_defconfig:
"
common/bouncebuf.c: In function âbounce_buffer_stopâ:
common/bouncebuf.c:82:34: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
82 | dma_unmap_single((dma_addr_t)state->bounce_buffer,
| ^
"
The warning is valid, the pointer has to be up-cast first.
