powerpc/85xx: Add local_irq_restore in error handling code
There is a call to local_irq_restore in the normal exit case, so it would seem that there should be one on an error return as well. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression l; expression E,E1,E2; @@ local_irq_save(l); ... when != local_irq_restore(l) when != spin_unlock_irqrestore(E,l) when any when strict ( if (...) { ... when != local_irq_restore(l) when != spin_unlock_irqrestore(E1,l) + local_irq_restore(l); return ...; } | if (...) + {local_irq_restore(l); return ...; + } | spin_unlock_irqrestore(E2,l); | local_irq_restore(l); ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
