Subject: [PATCH 6/9] phy: phy-spear1340-miphy: Remove unncessary site specific OOM messages
Date: Fri, 15 Aug 2014 13:40:13 +0100 [thread overview]
Message-ID: <1408106416-19044-7-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1408106416-19044-1-git-send-email-peter.griffin@linaro.org>
The site specific OOM messages are unncessary, because they duplicate
messages from the memory subsystem which include dump_stack().
Removing these superflous messages makes the kernel smaller. A discussion
here http://patchwork.ozlabs.org/patch/324158/ found that all error paths
from kzalloc will print a error message, and that any error path which maybe
found which doesn't would be considered a bug in kzalloc.
