[lvc-project] [PATCH 0/3] staging: media: av7110: check demux and net initialization in av7110_register()

[Andrey Karelin]

av7110_register() ignores the return values of dvb_dmx_init(),
dvb_dmxdev_init() and dvb_net_init() for both the main and the optional
budget-patch demux. On failure probing continues with half-initialized
objects, which leads to NULL pointer dereferences on first use or on
device removal. av7110_attach() does not call dvb_unregister() when
av7110_register() fails, so with this series av7110_register() unwinds
what it has set up on its own.
