Messages in this thread Patch in this message |  | | Subject | [PATCH v2 17/22] drivers/base: Make device_find_child_by_name() compatible with sysfs inputs | From | Dan Williams <> | Date | Sun, 12 Jul 2020 09:27:37 -0700 |

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.
