From fa1f68db6ca7ebb6fc4487ac215bffba06c01c28 Mon Sep 17 00:00:00 2001 From: Samu Onkalo Date: Mon, 24 May 2010 14:33:10 -0700 Subject: [PATCH] drivers: misc: pass miscdevice pointer via file private data For misc devices, inode->i_cdev doesn't point to the device drivers own data. Link between file operations and device driver internal data is lost. Pass pointer to misc device struct via file private data for driver open function use.
