Revision 58e78475ec706f93e0cc049449ffd11fbfdadb3e authored by Jeff Mahoney on 27 June 2007, 21:09:58 UTC, committed by Linus Torvalds on 28 June 2007, 18:34:54 UTC
This patch changes the test for the thread pid from >= 0 to > 0.

When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver.  Part of shutting it
down includes tearing down the thread for tv audio.

The test for tearing down the thread tests for >= 0.  Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet.  We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

This bug was observed in Novell Bugzilla 284718, when request_irq() failed.
