Subject: [PATCH] tpm_tis: Move setting of TPM_CHIP_FLAG_IRQ into tpm_tis_probe_irq_single
Date: Tue, 12 Nov 2019 15:27:25 -0500	[thread overview]
Message-ID: <20191112202725.3009814-1-stefanb@linux.vnet.ibm.com> (raw)

From: Stefan Berger <stefanb@linux.ibm.com>

Move the setting of the TPM_CHIP_FLAG_IRQ for irq probing into
tpm_tis_probe_irq_single before calling tpm_tis_gen_interrupt.
This move handles error conditions better that may arise if anything
before fails in tpm_tis_probe_irq_single.
