[PATCH v4 1/5] tpm/st33zp24: Remove useless tpm_gen_interrupt

From: Jarkko Sakkinen
Date: Tue Jul 19 2016 - 19:45:47 EST

From: Jason Gunthorpe <jgunthorpe@xxxxxxxxxxxxxxxxxxxx>

This function should only be called as part of an IRQ probing protocol
and st33 does not have any code to detect that the IRQ it tries to
generate was not generated and disable the IRQ.

Since st33 is primarily a DT binding driver it should not be doing
IRQ probing anyhow, so let us just delete this useless call.
