Subject: [PATCH] ARM: fix v7M build for !CONFIG_PRINTK
Date: Sun, 11 Jan 2015 22:25:49 -0600 [thread overview]
Message-ID: <1421036749-5308-1-git-send-email-robh@kernel.org> (raw)
Minimal builds for v7M are broken when printk is disabled. The caller is
assembly so add the necessary ifdef around the call.
