Subject: tpm: compile out unused code in the PNP and PM cases
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e72fe73bfc7e4219b8dd212026c7113f4e37f91;p=linux-beck.git

tpm: compile out unused code in the PNP and PM cases

The tpm_tis driver doesn't use tpm_tis_resume except when PM is
configured and doesn't make use of tpm_tis_reenable_interrupts except
when PM or PNP is configured.
