Version 7 of this patchset performs a rebase to linux-4.9-rc4 and adjust the usage of strncasecmps to sysfs_streq. I have also renamed the function i2c_of_match_device_strip_vendor to i2c_of_match_device_sysfs which feels more appropriate now. Retested with successful usage of full compatible strings, and shortened device id's based on the vendor prefix being stripped. Wolfram, for your convenience this series is available as a tagged commit at: https://git.kernel.org/pub/scm/linux/kernel/git/kbingham/linux.git i2c-dt/v4.9-rc4-probe-conversion-v7, though this includes the TESTPATCH so it is not by itself suitable for a merge. Verifying the sysfs_streq usage can be seen below: root@arm:~# ./new_i2c_device ds1307 0x68 ds1307 0x68 > /sys/bus/i2c/devices/i2c-2/new_device [ 216.289958] rtc-ds1307 2-0068: rtc core: registered ds1307 as rtc0 [ 216.296740] rtc-ds1307 2-0068: 56 bytes nvram [ 216.301534] i2c i2c-2: new_device: Instantiated device ds1307 at 0x68 root@arm:~# root@arm:~# cat /sys/class/rtc/rtc0/date 2016-11-07 root@arm:~# cat /sys/class/rtc/rtc0/name ds1307 root@arm:~# ./delete_i2c_device 0x68 [ 237.018514] i2c i2c-2: delete_device: Deleting device ds1307 at 0x68 root@arm:~# ./new_i2c_device maxim,ds1307 0x68 maxim,ds1307 0x68 > /sys/bus/i2c/devices/i2c-2/new_device [ 243.346216] rtc-ds1307 2-0068: I'm a Maxim ...
