tpm_tis / PM: Fix unused function warning for CONFIG_PM_SLEEP

07368d32 · Rafael J. Wysocki <[email protected]> · 2012-08-09 23:00:35 +02:00

According to a compiler warning, the tpm_tis_resume() function is not
used for CONFIG_PM_SLEEP unset, so add a #ifdef to prevent it from
being built in that case.
