If anyone has any objections, please let me know. ------------------ From: Fabio Estevam commit 0f40cbc4f85e13b1a42ae2f41231645a14965872 upstream. cmd_err is used to handle error code, so it should not be unsigned. This fixes the following warning when building with W=1 option: drivers/i2c/busses/i2c-mxs.c: In function 'mxs_i2c_xfer_msg': drivers/i2c/busses/i2c-mxs.c:331:19: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] Signed-off-by: Fabio Estevam Acked-by: Marek Vasut Signed-off-by: Wolfram Sang [ herton: adjust context ] Signed-off-by: Herton Ronaldo Krzesinski --- drivers/i2c/busses/i2c-mxs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/i2c/busses/i2c-mxs.c b/drivers/i2c/busses/i2c-mxs.c index 04eb441..a505bce 100644 --- a/drivers/i2c/busses/i2c-mxs.c +++ b/drivers/i2c/busses/i2c-mxs.c @@ -110,7 +110,7 @@ struct mxs_i2c_dev { struct device *dev; void __iomem *regs; struct completion cmd_complete; - u32 cmd_err; + int cmd_err; struct i2c_adapter adapter; };
