From e11f0f90a626f93899687b1cc909ee37dd6c5809 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Wed, 14 Jun 2017 19:30:03 +0900 Subject: ALSA: pcm: remove SNDRV_PCM_IOCTL1_INFO internal command Drivers can implement 'struct snd_pcm_ops.ioctl' to handle some requests from ALSA PCM core. These requests are internal purpose in kernel land. Usually common set of operations are used for it. SNDRV_PCM_IOCTL1_INFO is one of the requests. According to code comment, it has been obsoleted in the old days. We can see old releases in ftp.alsa-project.org. The command was firstly introduced in v0.5.0 release as SND_PCM_IOCTL1_INFO, to allow drivers to fill data of 'struct snd_pcm_channel_info' type. In v0.9.0 release, this was obsoleted by the other commands for ioctl(2) such as SNDRV_PCM_IOCTL_CHANNEL_INFO. This commit removes the long-abandoned command, bye.
