From 9c8c5742b6af76a3fd93b4e56d1d981173cf9016 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 25 Oct 2019 11:14:48 +0200 Subject: tpm: Switch to platform_get_irq_optional() platform_get_irq() calls dev_err() on an error. As the IRQ usage in the tpm_tis driver is optional, this is undesirable. Specifically this leads to this new false-positive error being logged: [ 5.135413] tpm_tis MSFT0101:00: IRQ index 0 not found This commit switches to platform_get_irq_optional(), which does not log an error, fixing this.
