Herton Ronaldo Krzesinski Dec. 13, 2012, 1:57 p.m. -stable review patch.  If anyone has any objections, please let me know.


From: Guenter Roeck <linux@roeck-us.net>

commit aa1e3e81e75ceb3d977c3292cefafcd5179eb8b8 upstream.

When allocating the memory for i2c busses, the code checked the wrong
variable and thus never detected if there was a memory error.
