Check fops_get() return value

2009-01-06T23:59:11Z

Several subsystem open handlers dereference the fops_get() return value without checking it for nullness. This opens a race condition between the open handler and module unloading. A module can be marked as being unloaded (MODULE_STATE_GOING) before its exit function is called and gets the chance to unregister the driver. During that window open handlers can still be called, and fops_get() will fail in try_module_get() and return a NULL pointer. This change checks the fops_get() return value and returns -ENODEV if NULL.

V4L/DVB (9490): linux-next: v4l-dvb tree build failure

2008-12-29T19:53:25Z

Today's linux-next build (x86_64 allmodconfig) failed like this: drivers/media/dvb/dvb-core/dvbdev.c: In function 'dvb_register_device': drivers/media/dvb/dvb-core/dvbdev.c:254: error: implicit declaration of function 'nums2minor' Caused by commit f3d9182030d9655d9ffff33dfceb45b4a127b6ec ("V4L/DVB (9361): Dynamic DVB minor allocation") which clearly has not even been built with CONFIG_DVB_DYNAMIC_MINORS=y.

V4L/DVB (9473): add DVB_DEVICE_NUM and DVB_ADAPTER_NUM to uevent

2008-12-29T19:53:24Z

This allows udev to create proper device nodes without any hacky shell scripts/programs to call, which guess these numbers from the kernel device names. Signed-off-by: Kay Sievers Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (9361): Dynamic DVB minor allocation

2008-12-29T19:53:12Z

Implement dynamic minor allocation for DVB, to allow more than four devices of the same type per adapter, based on drivers/usb/core/file.c. Add a new config option, DVB_DYNAMIC_MINORS, to make use of this feature, which defaults to no for backwards compatibility. Signed-off-by: Andreas Oberritter Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (9227): MFE: Add multi-frontend mutual exclusion

2008-10-17T20:24:15Z

This add frontend R/W mutual exclusion. Prior to this point in time it was possible to open both frontends simultaneously which an MFE card cannot support. In order to stop this, a delayed open is performed which has the following function: - Return EBUSY after a configurable amount of time if a frontend is unavailable due to the other being in use. - Only allow opening of a frontend if the kernel thread of the other has stopped. This solution was chosen to allow switching between frontends to work as seamlessly as possible. When both frontends are actually opened simultaneously then one will only open, but if quick switching is performed between one of many then the new open will succeed in a clean fashion rather than interrupting a kernel thread.

device create: misc: convert device_create_drvdata to device_create

Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman
