[linux-yocto] [PATCH 06/25] FogBugz #532583-2: hwmon: Fix buffer calls for SDL compliance.

[Meng.Li at windriver.com]

From: Thor Thayer <thor.thayer at linux.intel.com>

commit  b899ea69f0346f24ef238bcb248bde51dc639ea2 from
https://github.com/altera-opensource/linux-socfpga.git

The buffer calls need to be more secure so pass the buffer size
in the sprintf functions. Limit buffer size to 5.
