Instead of just ignoring errors related to getting the vbus regulator yield at least a warning message. This would have saved me some debugging time when trying to understand why USB doesn't work without the right regulator driver enabled. Note that machines that don't define a regulator in their device tree don't issue this warning as regulator_get() returns the dummy regulator in this case. The alternative to error out wasn't accepted because this probably creates regressions for regulators that are default-on but without a driver in barebox. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx> --- Hello, (implicit) v1 was sent some time ago with Message-ID: <1485d35a-d55b-2440-4852-1737e78f8aa1@xxxxxxxxxxxxxx>. Ahmad suggested to use %pe instead of strerror(-ret). This is also the only change compared to the first submission.
