From: Clemens Ladisch Date: Mon, 12 Dec 2005 08:33:37 +0000 (+0100) Subject: [ALSA] seq: set client name in snd_seq_create_kernel_client() X-Git-Tag: v2.6.16-rc1~474^2~22^2~3^2~26 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7b6d92451ad5e1136dc347347e888b94638b8ba9;p=linux-2.6 [ALSA] seq: set client name in snd_seq_create_kernel_client() All users of snd_seq_create_kernel_client() have to set the client name anyway, so we can just pass the name as parameter. This relieves us from having to muck around with a struct snd_seq_client_info in these cases.
