From: Takashi Iwai Date: Tue, 14 Apr 2009 14:13:58 +0000 (+0200) Subject: ALSA: add private_data to struct snd_jack X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9d59065cd6fae841ca56c281189d5b8d0817d35f;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ALSA: add private_data to struct snd_jack Added private_data and private_free fields to struct snd_jack so that the caller can assign the data. It'll be helpful for avoiding the double-free of the jack instance.
