Shang XiaoJing 5e4500454d parisc: led: Fix potential null-ptr-deref in start_task() commit 41f563ab3c33698bdfc3403c7c2e6c94e73681e4 upstream. start_task() calls create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen: start_task() create_singlethread_workqueue() # failed, led_wq is NULL queue_delayed_work() queue_delayed_work_on() __queue_delayed_work() # warning here, but continue __queue_work() # access wq->flags, null-ptr-deref Check the ret value and return -ENOMEM if it is NULL. Fixes: `3499495205` ("[PARISC] Use work queue in LED/LCD driver instead of tasklet.")

/*
** HP VISUALIZE Workstation PCI Bus Defect
**
** "HP has discovered a potential system defect that can affect
** the behavior of five models of HP VISUALIZE workstations when
** equipped with third-party or customer-installed PCI I/O expansion
** cards. The defect is limited to the HP C180, C160, C160L, B160L,
** and B132L VISUALIZE workstations, and will only be encountered
** when data is transmitted through PCI I/O expansion cards on the
** PCI bus. HP-supplied graphics cards that utilize the PCI bus are
** not affected."

**	Product		First Good Serial Number
**  C200/C240 (US)	US67350000
**B132L+/B180 (US)	US67390000
**   C200 (Europe)	3713G01000

** Note that many boards were fixed/replaced under a free replacement
** program. Assume a machine is only "suspect" until proven otherwise.
