2007-08-15DVB: convert struct class_device to struct deviceMichael Krufky
From: Kay Sievers <kay.sievers@vrfy.org> The currently used "struct class_device" will be removed from the kernel. Here is a trivial patch that converts DVB to use struct device. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>
2007-08-09dvb_frontend: Fixed GET_INFO ioctl and check of frequency limitsOliver Endriss

2007-08-01Frontend_ioctl(): fix check-after-useMauro Carvalho Chehab
From: Adrian Bunk <bunk@stusta.de> The Coverity checker spotted that we have already oops'ed if "fe" was NULL. Since "fe" being NULL seems impossible at this point this patch removes the NULL check.

2007-07-19backport kernel changeset 831441862956fffa17b9801db37e6ea1650b0f69Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> kernel-sync: Original patch description from the patch by Rafael J. Wysocki <rjw@sisk.pl>: Freezer: make kernel threads nonfreezable by default Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-07-02Fix v4l-dvb backward compatibilityMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Due to several internal API changes on kernel, kernel backward compatibility were lost. Basically, compat.h should be the last include for it to work properly. This patch basically reorders kernel headers to allow backward compat to work fine. Also: Some includes were added after some non-include macros, on old drivers. Better to keep all includes at the beginning of the files. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-06-01Improve compatibility handlingMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> V4L/DVB tree keeps backward compatibility with vanilla 2.6.x kernels. However, if some API changes happens on 2.6.x.y, this wouldn't be handled. This patch improves the compatibility capabilities of the tree by allowing customized scripts to be added on make_config_compat.pl. So, when generating config-compat.h, some compat checks can be done against the kernel tree. The practical effect is allowing compilation on 2.6.17.x trees, used by several distros, where some changes on netdevice.h affects dvb-net, stopping its compilation.

2007-05-06dvb-core: Handle failures to create devicesTrent Piepho
From: Simon Arlott <simon@fire.lp0.eu> dvb-core is not started early enough when device drivers that use dvb are compiled in so dvb_register_device fails (silently) since dvb_class is NULL, this runs dvb_init using subsys_initcall instead of module_init. dvb_register_device will now check the return value of class_device_create.

2007-03-10Core: fix several locking related problemsMauro Carvalho Chehab
From: Simon Arlott <simon@fire.lp0.eu> Fix several instances of dvb-core functions using mutex_lock_interruptible and returning -ERESTARTSYS where the calling function will either never retry or never check the return value. These cause a race condition with dvb_dmxdev_filter_free and dvb_dvr_release, both of which are filesystem release functions whose return value is ignored and will never be retried. When this happens it becomes impossible to open dvr0 again (-EBUSY) since it has not been released properly.

From: Steven Toth <stoth@hauppauge.com> This patch enables generic bus arbitration callbacks enabling dvbcore frontend_open and frontend_release to pass 'acquire' and 'release' hardware messages back into the DVB bridge frameworks. Frameworks like cx88 can then implement single bus multiple demod card sharing features, which would prohibit two frontends from attempting to use a single transport bus at the same time.

From: Andrew de Quincey <adq_dvb@lidskialf.net> The changes to add frontend reinitialisation moved the position where the init() op is called into the frontend thread.
