+Subject: [PATCH 123/182] 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.
