Subject: [RESEND PATCH v3] tpm: st33zp24: remove pointless checks on probe
Date: Tue, 6 Dec 2022 17:44:57 -0800 [thread overview]
Message-ID: <Y4/wGWTgYfR/Jb9D@google.com> (raw)
Remove tests for SPI device or I2C client to be non-NULL because
driver core will never call driver's probe method without having
a valid device structure.
Reviewed-by: Jarkko Sakkinen <jarkko@kernel.org>

v3: no changes
v2: reworked commit message
This was a part of a 3-patch series, the first 2 dealt with dropping
support for platform data and converting the driver to gpiod API, and
were applied, this one got reviewed-by from Jarkko but for some reason
was left out.
