[ 43/46] i2c: mxs: Fix type of error code

From: Greg Kroah-Hartman
Date: Thu Jan 24 2013 - 16:29:25 EST


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

------------------

From: Fabio Estevam <fabio.estevam@xxxxxxxxxxxxx>

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]
