Subject: [PATCH v2 1/3] ata: ahci_platform: fix ahci_platform_data->suspend
 method handling

Looking at ST SPEAr1340 AHCI code (the only user of the deprecated
pdata->suspend and pdata->resume) it is obvious the we should return
after calling pdata->suspend() only if the function have returned
non-zero return value.  The code has been broken since commit 1e70c2
("ata/ahci_platform: Add clock framework support").  Fix it.
