[PATCH 0/2] Correctly handle plaform_get_irq()'s result in the libata drivers

Here are 2 patches against the 'master' branch of the Jens Axboe's 'linux-block.git' repo.
The affected drivers call platform_get_irq() but mis-interprete its result -- they consider
IRQ0 as error and the real error codes as valid IRQs... :-/

[1/2] pata_arasan_cf: fix IRQ check
[2/2] pata_ipx4xx_cf: fix IRQ check
