Julia Lawall e2bde78713 mfd: Fix davinci memory leak 
Error handling code following a kmalloc should free the allocated data.

The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
statement S;
expression E;

print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line)
