platform_get_irq() has already checked and printed the return value,
the printing here is nothing special, it is not necessary at all.

Hello again. :-)
Now, 2 patches to the different files shouldn't have and identical subject! And the patch
subject should reflect the exact patch locus, e.g. "sata_highbank: delete redundant printing
of return value".

Again, this code has more serious issue: it breaks deferred probing by
overriding the result to -EINVAL...

Hello!
The patch subject should reflect the exact patch locus, e.g. "ata: libahci_platform:
delete redundant printing of return value".

This code has more serious problem: it returns 0 on error as if it was success.
Should be changed to *if* (irq < 0) (in a separate patch).
