Subject: Fwd: [PATCH] bus: fsl-mc: replace snprintf in show functions with
 sysfs_emit

show() should not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/media/i2c/ccs/ccs-core.c:3761: WARNING: use scnprintf or 
sprintf.

./drivers/bus/fsl-mc/fsl-mc-bus.c:204:8-16: WARNING: use scnprintf or 
sprintf
