[PATCH v2] pata_ipx4xx_cf: Fix unsigned comparison with less than zero

[PATCH v2] pata_ipx4xx_cf: Fix unsigned comparison with less than zero

[angkery]

From: Junlin Yang <yangjunlin@yulong.com>

The return from the call to platform_get_irq() is int, it can be
a negative error code, however this is being assigned to an unsigned
int variable 'irq', so making 'irq' an int, and change the position to
keep the code format.

Fixes coccicheck warnings:
./drivers/ata/pata_ixp4xx_cf.c:168:5-8:
WARNING: Unsigned expression compared with zero: irq < 0

changes in v1:
update the commit information.
changes in v2:
As Sergei said, it should read irq < 0, update commit information.
