Hello,
My board has powerpc 885 microcontroler. Temperature sensor is an LM74.
Kernel has CONFIG_SPI_FSL_SPI and CONFIG_SPI_FSL_CPM and CONFIG_SENSORS_LM70.
Since kernel 5.10, 'sensors' reports temperature 0°C on my board:
root@vgoip:~# sensors
lm74-spi-0-5 Adapter: SPI adapter temp1: +0.0 C
lm74-spi-0-1 Adapter: SPI adapter temp1: +0.0 C
With commit 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors") reverted, it is back to work:
root@vgoip:~# sensors
lm74-spi-0-5 Adapter: SPI adapter temp1: +38.9 C
lm74-spi-0-1 Adapter: SPI adapter temp1: +37.2 C
What shall I do ?
Thanks Christophe
