Subject: dm: core: remove unnecessary return condition in uclass lookup
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=17b28edb37a33d0c89089faf36e4edd7084f65fa;p=project%2Fbcm63xx%2Fu-boot.git

dm: core: remove unnecessary return condition in uclass lookup

These conditions never happen.
 - There is no real uclass with UCLASS_INVALID id.
 - uclass never becomes NULL because ll_entry_start() always returns
   a valid pointer.
