commit a595c1ce4c9d572cf53513570b9f1a263d7867f2 upstream.

We weren't checking whether the resource was in use before calling
res_free(), so applications which called STREAMOFF on a v4l2 device that
wasn't already streaming would cause a BUG() to be hit (MythTV).

If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised. Move it up to the earliest point we can, right after calling rc_allocate_device().

quickly enough, we may enable interrupts and try to use ite_dev::rdev
before it has been initialised.  Move it up to the earliest point we

media: Avoid sysfs oops when an rc_dev's raw device is absent 2012-10-02T16:47:52+00:00 Douglas Bagnall douglas@paradise.net.nz 2012-07-07T02:27:57+00:00 abfbc26e32cd42374213c90766a5f416ad58732c commit 720bb6436ff30fccad05cf5bdf961ea5b1f5686d upstream. For some reason, when the lirc daemon learns that a usb remote control has been unplugged, it wants to read the sysfs attributes of the disappearing device. This is useful for uncovering transient inconsistencies, but less so for keeping the system running when such inconsistencies exist. Under some circumstances (like every time I unplug my dvb stick from my laptop), lirc catches an rc_dev whose raw event handler has been removed (presumably by ir_raw_event_unregister), and proceeds to interrogate the raw protocols supported by the NULL pointer. This patch avoids the NULL dereference, and ignores the issue of how this state of affairs came about in the first place. Version 2 incorporates changes recommended by Mauro Carvalho Chehab (-ENODEV instead of -EINVAL, and a signed-off-by).
