Subject: leds: turris-omnia: Drop unnecessary mutex locking
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Do not lock driver mutex in the global LED panel brightness sysfs
accessors brightness_show() and brightness_store().
The mutex locking is unnecessary here. The I2C transfers are guarded by
I2C core locking mechanism, and the LED commands itself do not interfere
with other commands.

Subject: leds: turris-omnia: Do not use SMBUS calls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The leds-turris-omnia driver uses three function for I2C access:
- i2c_smbus_write_byte_data() and i2c_smbus_read_byte_data(), which
cause an emulated SMBUS transfer,
- i2c_master_send(), which causes an ordinary I2C transfer.
The Turris Omnia MCU LED controller is not semantically SMBUS, it
operates as a simple I2C bus. It does not implement any of the SMBUS
specific features, like PEC, or procedure calls, or anything. Moreover
the I2C controller driver also does not implement SMBUS, and so the
emulated SMBUS procedure from drivers/i2c/i2c-core-smbus.c is used for
the SMBUS calls, which gives an unnecessary overhead.
When I first wrote the driver, I was unaware of these facts, and I
simply used the first function that worked.
Drop the I2C SMBUS calls and instead use simple I2C transfers.

Subject: [PATCH] hwrng: geode: fix accessing registers
When the membase and pci_dev pointer were moved to a new struct in priv,
the actual membase users were left untouched, and they started reading
out arbitrary memory behind the struct instead of registers. This
unfortunately turned the RNG into a constant number generator, depending
on the content of what was at that offset.
To fix this, update geode_rng_data_{read,present}() to also get the
membase via amd_geode_priv, and properly read from the right addresses
again.
Fixes: 9f6ec8dc574e ("hwrng: geode - Fix PCI device refcount leak")
