Re: [PATCH] tpm: Switch to platform_get_irq_optional()

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()"), platform_get_irq() will call 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.

Cc: stable@vger.kernel.org # 5.4.x

Incorrect format (should be wo '<' and '>').

Also, not sure why this should be backported to stable kernel anyway.
