Merge tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging
Pull hwmon fixes from Guenter Roeck: - Error path fixes for abituguru and iio_hwmon drivers. - Drop erroneously created attributes from nct6775 driver. - Drop redundant safety on cache lifetime for tmp401 driver. - Add explicit maintainer for LM95234 and TMP401 drivers. * tag 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: MAINTAINERS: Add myself as maintainer for LM95234 and TMP401 drivers hwmon: (tmp401) Drop redundant safety on cache lifetime hwmon: fix error return code in abituguru_probe() hwmon: (iio_hwmon) Fix null pointer dereference hwmon: (nct6775) Do not create non-existing attributes hwmon: (iio_hwmon) Fix missing iio_channel_release_all call if devm_kzalloc fail
