tpm: Fix suspend regression
Fix the suspend regression due to the wrong way of retrieving the chip structure. The suspend functions are attached to the hardware device, not the chip and thus must rely on drvdata. Fixes: e89f8b1ade9cc1a ("tpm: Remove all uses of drvdata from the TPM Core") Reported-by: Jeremiah Mahler <jmmahler@gmail.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Tested-by: Jeremiah Mahler <jmmahler@gmail.com> Acked-by: Jarkko Sakkinen <jarkko.sakkine@linux.intel.com> Signed-off-by: Jarkko Sakkinen <jarkko.sakkine@linux.intel.com>
