If anyone has any objections, please let me know. ------------------ From: Bartlomiej Zolnierkiewicz commit 27aa64b9d1bd0d23fd692c91763a48309b694311 upstream. Add missing clk_put() call to ata_host_activate() failure path. Sergei says, "Hm, I have once fixed that (see that *if* (!ret)) but looks like a later commit 477c87e90853d136b188c50c0e4a93d01cad872e (ARM: at91/pata: use gpio_is_valid to check the gpio) broke it again. :-( Would be good if the changelog did mention that..."
