ata: pata_imx: fix devm_ioremap_resource() return value checking
devm_ioremap_resource() returns a pointer to the remapped memory or an ERR_PTR() encoded error code on failure. Fix the check inside pata_imx_probe() accordingly. Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Tejun Heo <tj@kernel.org>
