The patch titled Subject: drivers/base: make device_find_child_by_name() compatible with sysfs inputs has been added to the -mm tree. Its filename is drivers-base-make-device_find_child_by_name-compatible-with-sysfs-inputs.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/drivers-base-make-device_find_child_by_name-compatible-with-sysfs-inputs.patch and later at https://ozlabs.org/~akpm/mmotm/broken-out/drivers-base-make-device_find_child_by_name-compatible-with-sysfs-inputs.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Dan Williams <dan.j.williams@xxxxxxxxx> Subject: drivers/base: make device_find_child_by_name() compatible with sysfs inputs Use sysfs_streq() in device_find_child_by_name() to allow it to use a sysfs input string that might contain a trailing newline. The other "device by name" interfaces, {bus,driver,class}_find_device_by_name(), already account for sysfs strings.
