[PATCH] tpm: tpm_tis: Fix compile problems with CONFIG_PM_SLEEP/CONFIG_PNP
From: Jason Gunthorpe
Date: Sun Nov 03 2013 - 22:48:29 EST
If CONFIG_PM_SLEEP=n, CONFIG_PNP=y we get this warning:
drivers/char/tpm/tpm_tis.c:706:13: warning: 'tpm_tis_reenable_interrupts' defined but not used [-Wunused-function]
This seems to have been introduced in a2fa3fb0d 'tpm: convert tpm_tis driver
to use dev_pm_ops from legacy pm_ops'
Also, unpon reviewing, the #ifdefs around tpm_tis_pm are not right, the first
reference is protected, the second is not. tpm_tis_pm is always defined so we can drop
the #ifdef.
