Subject: [PATCH] tpm: Switch to platform_get_irq_optional()
Date: Sat, 19 Oct 2019 11:45:28 +0200 [thread overview]
Message-ID: <20191019094528.27850-1-hdegoede@redhat.com> (raw)
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.
