Subject: [PATCH 00/31] hwmon: convert i2c_smbus_read_block_data() users to pass buffer length
Date: Sat, 24 Oct 2026 20:06:03 -0700 [thread overview]
Message-ID: <20261024-hwmon-i2c-smbus-read-block-data-v1-0-e81941ad0cd3@gmail.com> (raw)
Convert all callers of i2c_smbus_read_block_data() across the hwmon
and PMBus subsystems to pass destination buffer sizes, adopting the
4-argument form introduced in commit 68f382641f8c ("i2c: smbus: make
i2c_smbus_read_block_data() safer").
For drivers that used intermediate bounce buffers (lineage-pem, lm93,
and pt5161l), redundant buffer allocations and memcpy() calls are
dropped so data is read directly into target structures.
For drivers performing string comparisons on the read data
(acbel-fsg032, bpa-rs600, ltc4286, max15301, pim4328, and stpddc60),
ensure the destination buffer is explicitly NUL-terminated before
comparison, and pass a length that reserves space for the terminator.
