Subject: [PATCH v2 32/41] ARM: s3c24xx: bast: avoid irq_desc array usage

From: Arnd Bergmann <arnd@...db.de>

Once we move to sparse irqs, the irq_desc[] array is no
longer accessible, so replace the two uses in bast-irq.c.
The first one can use irq_to_desc(), the second one seems
completely unneeded as we already have a pointer to the
correct descriptor.
