i2c: mxs: Fix type of error code
Fabio Estevam [Tue, 8 Jan 2013 00:32:06 +0000 (22:32 -0200)]
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]
