Subject: [PATCH] char/tpm: Fix compile error if CONFIG_PM is not set in tpm_i2c_infineon

If CONFIG_PM was not set the compiler aborted with the following message:
tpm_i2c_infineon.c:740:12: error: lvalue required as unary '&' operand

This patch fixes this error by not defining tpm_tis_i2c_ops as NULL if
CONFIG_PM is not set, but only setting the suspend and resume function
pointer as NULL

Signed-off-by: Peter Huewe <peter.huewe@...ineon.com>

Sorry for the inconvenience - now tested with and without CONFIG_PM. Sorry.
