ata: brcm: mark PM functions as __maybe_unused
The new shutdown callback causes a link failure: drivers/ata/ahci_brcm.c: In function 'brcm_ahci_shutdown': drivers/ata/ahci_brcm.c:552:8: error: implicit declaration of function 'brcm_ahci_suspend'; did you mean 'brcm_ahci_shutdown'? [-Werror=implicit-function-declaration] ret = brcm_ahci_suspend(&pdev->dev); ^~~~~~~~~~~~~~~~~ Remove the incorrect #ifdef and use __maybe_unused annotations instead to make this more robust. Fixes: 7de9b1688c1d ("ata: ahci_brcm: Add a shutdown callback") Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
