question about setting TPM_CHIP_FLAG_IRQ in tpm_tis_core_init

[Jerry Snitselaar]

Question about 1ea32c83c699 ("tpm_tis_core: Set TPM_CHIP_FLAG_IRQ before probing for interrupts").
Doesn't tpm_tis_send set this flag, and setting it here in tpm_tis_core_init short circuits what
tpm_tis_send was doing before? There is a bug report of an interrupt storm from a tpm on a t490s laptop
with the Fedora 31 kernel (5.3), and I'm wondering if this change could cause that. Before they got
the warning about interrupts not working, and using polling instead.
