In big endian cases, __constant_cpu_to_be16 and cpu_to_be16 expand directly to the same expression. So, replace __constant_cpu_to_be16 with cpu_to_be16 with the goal of getting rid of the definition of __constant_cpu_to_be16 completely. The semantic patch that performs this transformation is as follows: @@expression x;@@ - __constant_cpu_to_be16(x) + cpu_to_be16(x) Signed-off-by: Vaishali Thakkar --- drivers/media/i2c/s5k5baf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/media/i2c/s5k5baf.c b/drivers/media/i2c/s5k5baf.c index 297ef04..7a43b55 100644 --- a/drivers/media/i2c/s5k5baf.c +++ b/drivers/media/i2c/s5k5baf.c @@ -491,7 +491,7 @@ static void s5k5baf_write_arr_seq(struct s5k5baf *state, u16 addr, v4l2_dbg(3, debug, c, "i2c_write_seq(count=%d): %*ph\n", count, min(2 * count, 64), seq); - buf[0] = __constant_cpu_to_be16(REG_CMD_BUF); + buf[0] = cpu_to_be16(REG_CMD_BUF); while (count > 0) { int n = min_t(int, count, ARRAY_SIZE(buf) - 1); -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
