Subject: [PATCH 4.15 121/146] tpm: remove unused variables

4.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@...db.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.

Fixes: 6d0866cbc2d3 ("tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()")
