Subject: [PATCH 12/31] hwmon: (pmbus/fsp-3y) use 4-argument i2c_smbus_read_block_data()
Date: Sat, 24 Oct 2026 20:06:15 -0700 [thread overview]
Message-ID: <20261024-hwmon-i2c-smbus-read-block-data-v1-12-e81941ad0cd3@gmail.com> (raw)
In-Reply-To: <20261024-hwmon-i2c-smbus-read-block-data-v1-0-e81941ad0cd3@gmail.com>
Pass sizeof(buf) - 1 to i2c_smbus_read_block_data() in fsp3y_detect()
to leave room for the NUL terminator.
