i2c: mxs: Fix type of error code
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 <fabio.estevam@freescale.com> Acked-by: Marek Vasut <marex@denx.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
