Hongling Zeng 37b0dc5e27 parisc: Fix IRQ leak in LASI driver
When request_irq() succeeds but gsc_common_setup() fails later,
the IRQ is never released. Fix this by adding proper error handling
with goto labels to ensure resources are released in LIFO order.

Detected by Smatch:
  drivers/parisc/lasi.c:216 lasi_init_chip() warn: 'lasi->gsc_irq.irq'
from request_irq() not released on lines: 207.

** 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."

**   C200 (Europe)	3713G01000

** Note that many boards were fixed/replaced under a free replacement
