From: Julia Lawall <Julia.Lawall@...6.fr>
To: Jaroslav Kysela <perex@...ex.cz>
Cc: kernel-janitors@...r.kernel.org, Takashi Iwai <tiwai@...e.com>,
alsa-devel@...a-project.org, linux-kernel@...r.kernel.org
Subject: [PATCH] ALSA: pcm: constify action_ops structures
The action_ops structures are never modified, so declare them as const.
Done with the help of Coccinelle.
Signed-off-by: Julia Lawall <Julia.Lawall@...6.fr>
