From 4e0710a2d007032c8a82ef3af45a0e6e9176a2a7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 24 Apr 2022 23:31:00 -0600 Subject: dm: core: Allow finding a uclass device by partial name In some cases two devices are related and the only way to tell is to check that the names partially patch. Add a way to check this without needing to create a new string for the comparison. Fix the comment for device_find_child_by_namelen() while we are here.
