Subject: drivers: misc: pass miscdevice pointer via file private data
From: Samu Onkalo <samu.p.onkalo@xxxxxxxxx>
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.
