Subject: [PATCH v3 14/23] drivers/base: Make device_find_child_by_name() compatible with sysfs inputs
Date: Fri, 31 Jul 2020 20:26:18 -0700 [thread overview]
Message-ID: <159625237843.3040297.3301494256713690273.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <159625229779.3040297.11363509688097221416.stgit@dwillia2-desk3.amr.corp.intel.com>
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.
