From: Arnd Bergmann arnd@arndb.de

commit 68021bf4734d15c9a9ed1c1072b9ebcfda3e39cc upstream.

The CLKRUN fix caused a few harmless compile-time warnings:

drivers/char/tpm/tpm_tis.c: In function 'tpm_tis_pnp_remove': drivers/char/tpm/tpm_tis.c:274:23: error: unused variable 'priv' [-Werror=unused-variable] drivers/char/tpm/tpm_tis.c: In function 'tpm_tis_plat_remove': drivers/char/tpm/tpm_tis.c:324:23: error: unused variable 'priv' [-Werror=unused-variable]

This removes the variables that have now become unused.
