commit e96875677fb2b7cb739c5d7769824dff7260d31d upstream.
Account for all properties when a and/or b are 0:
gcd(0, 0) = 0
gcd(a, 0) = a
gcd(0, b) = b
Fixes no known problems in current kernels.

lib: add lib/gcd.c2009-06-18T20:04:05ZFlorian Fainelliflorian@openwrt.org2009-06-17T23:28:38Zurn:sha1:d2829224619866daf336141b71550e223a198838
This patch adds lib/gcd.c which contains a greatest common divider
implementation taken from sound/core/pcm_timer.c
Several usages of this new library function will be sent to subsystem
maintainers.
[akpm@linux-foundation.org: use swap() (pointed out by Joe)]
[akpm@linux-foundation.org: just add gcd.o to obj-y, remove Kconfig changes]
