Subject: dm: core: Remove unbind operations when not required
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=7f9875e733b79556ade508b88f88ac1f8a2c7e3c;p=u-boot.git

dm: core: Remove unbind operations when not required

The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing
devices. It should also remove the 'unbind' code since if we cannot
remove we probably don't need to unbind.
