[PATCH] [media] mx3_camera: use %pad format string for dma_ddr_t
From: Arnd Bergmann <arnd@arndb.de>
Date: 2016-02-01 16:46:16
The mx3_camera driver prints DMA addresses using the "%x" format
string, which is wrong when using a 64-bit dma_addr_t definition:
media/platform/soc_camera/mx3_camera.c: In function 'mx3_cam_dma_done':
media/platform/soc_camera/mx3_camera.c:149:125: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=]
media/platform/soc_camera/mx3_camera.c: In function 'mx3_videobuf_queue':
media/platform/soc_camera/mx3_camera.c:317:119: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=]
media/platform/soc_camera/mx3_camera.c: In function 'mx3_videobuf_release':
media/platform/soc_camera/mx3_camera.c:346:119: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Werror=format=]
This changes the code to use the special %pad format string, which
always does the right thing.

Another old bug that only rarely shows up in ARM randconfigs.
