[ Upstream commit 3481551f035725fdc46885425eac3ef9b58ae7b7 ]
This driver doesn't have of_match_table. This makes the kernel module tmp401.ko lack alias patterns (e.g: of:N*T*Cti,tmp411) to match DT node of the supported devices hence this kernel module will not be automatically loaded.
After adding of_match_table to this driver, the folllowing alias will be added into tmp401.ko. $ modinfo drivers/hwmon/tmp401.ko filename: drivers/hwmon/tmp401.ko ...... author: Hans de Goede hdegoede@redhat.com alias: of:N*T*Cti,tmp435C* alias: of:N*T*Cti,tmp435 alias: of:N*T*Cti,tmp432C* alias: of:N*T*Cti,tmp432 alias: of:N*T*Cti,tmp431C* alias: of:N*T*Cti,tmp431 alias: of:N*T*Cti,tmp411C* alias: of:N*T*Cti,tmp411 alias: of:N*T*Cti,tmp401C* alias: of:N*T*Cti,tmp401 ......
