Subject: ARM: OMAP: don't build hwspinlock in vain
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=be89cd9db41d7e39e8bebc71aee86938ee675f9c;p=deliverable%2Flinux.git

ARM: OMAP: don't build hwspinlock in vain

Cleanup: don't build mach-omap2/hwspinlock.c if the OMAP hwspinlock
driver isn't configured.

This will both shorten build time and avoid registering a device
which isn't needed.
