From: Stefan Berger stefanb@linux.ibm.com Date: Thu, 29 Aug 2019 20:09:06 -0400 Subject: [PATCH] tpm_tis_core: Set TPM_CHIP_FLAG_IRQ before probing for interrupts

The tpm_tis_core has to set the TPM_CHIP_FLAG_IRQ before probing for interrupts since there is no other place in the code that would set it.
