[PATCH] fm10k: mark PM functions as __maybe_unused

From: Arnd Bergmann
Date: Wed Oct 11 2017 - 09:59:04 EST


A cleanup of the PM code left an incorrect #ifdef in place, leading
to a harmless build warning:

drivers/net/ethernet/intel/fm10k/fm10k_pci.c:2502:12: error: 'fm10k_suspend' defined but not used [-Werror=unused-function]
drivers/net/ethernet/intel/fm10k/fm10k_pci.c:2475:12: error: 'fm10k_resume' defined but not used [-Werror=unused-function]

It's easier to use __maybe_unused attributes here, since you
can't pick the wrong one.

Fixes: 8249c47c6ba4 ("fm10k: use generic PM hooks instead of legacy PCIe power hooks")
