Subject: [PATCH 3.19.y-ckt 195/196] [media] exynos4-is: fix a format string bug

3.19.8-ckt16 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Rasmus Villemoes <linux@...musvillemoes.dk>

commit 76a563675485849f6f9ad5b30df220438b3628c1 upstream.

Ironically, 7d4020c3c400 ("[media] exynos4-is: fix some warnings when
compiling on arm64") fixed some format string bugs but introduced a
new one. buf_index is a simple int, so it should be printed with %d,
not %pad (which is correctly used for dma_addr_t).

Fixes: 7d4020c3c400 ("[media] exynos4-is: fix some warnings when compiling on arm64")
