Subject: dm: core: Drop device removal error path when not supported
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5a87c4174d18fe40dcc847ba36853a9f15cb3e1e;p=project%2Fbcm63xx%2Fu-boot.git

dm: core: Drop device removal error path when not supported

When CONFIG_DM_DEVICE_REMOVE is not enabled, such as in SPL, we cannot
remove or unbind devices and do not expect to get errors when binding
and probing devices. So drop the error path to reduce code size.
