This is a note to let you know that I have just added a patch titled ALSA: seq: Drop superfluous error/debug messages after malloc failures to the linux-3.13.y-queue branch of the 3.13.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11-ckt36. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ---8<------------------------------------------------------------ From cfc2f28ecac6c901b0288d4fa5fd0d31e1652428 Mon Sep 17 00:00:00 2001 From: Takashi Iwai <tiwai@suse.de> Date: Tue, 10 Mar 2015 15:41:18 +0100 Subject: ALSA: seq: Drop superfluous error/debug messages after malloc failures commit 24db8bbaa3fcfaf0c2faccbff5864b58088ac1f6 upstream. The kernel memory allocators already report the errors when the requested allocation fails, thus we don't need to warn it again in each caller side.
