can-bcm: fix minor heap overflow
commit 0597d1b99fcfc2c0eada09a698f85ed413d4ba84 upstream. On 64-bit platforms the ASCII representation of a pointer may be up to 17 bytes long. This patch increases the length of the buffer accordingly. http://marc.info/?l=linux-netdev&m=128872251418192&w=2 Reported-by: Dan Rosenberg <drosenberg@vsecurity.com> Signed-off-by: Oliver Hartkopp <socketcan@hartkopp.net> CC: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: David S.
