[PATCH] net: stmmac: platform: Fix MDIO init for platforms without PHY

by Padmanabhan Rajanbabu

The current implementation of "stmmac_dt_phy" function initializes the MDIO platform bus data, even in the absence of PHY. This fix will skip MDIO initialization if there is no PHY present.

patch "iio: imu: st_lsm6dsx: Fix selection of ST_LSM6DS3_ID" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: imu: st_lsm6dsx: Fix selection of ST_LSM6DS3_ID to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From fb4fbc8904e786537e29329d791147389e1465a2 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold <stephan(a)gerhold.net> Date: Mon, 16 Dec 2019 13:41:20 +0100 Subject: iio: imu: st_lsm6dsx: Fix selection of ST_LSM6DS3_ID At the moment, attempting to probe a device with ST_LSM6DS3_ID (e.g. using the st,lsm6ds3 compatible) fails with: st_lsm6dsx_i2c 1-006b: unsupported whoami [69] ... even though 0x69 is the whoami listed for ST_LSM6DS3_ID. This happens because st_lsm6dsx_check_whoami() also attempts to match unspecified (zero-initialized) entries in the "id" array. ST_LSM6DS3_ID = 0 will therefore match any entry in st_lsm6dsx_sensor_settings (here: the first), because none of them actually have all 12 entries listed in the "id" array. Avoid this by additionally checking if "name" is set, which is only set for valid entries in the "id" array. Note: Although the problem was introduced earlier it did not surface until commit 52f4b1f19679 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1") because ST_LSM6DS3_ID was the first entry in st_lsm6dsx_sensor_settings.
