Re: [PATCH v2] 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.

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()" Cc: stable@vger.kernel.org # 5.4.x Signed-off-by: Hans de Goede hdegoede@redhat.com
