While this change was intended to fix a mistake in the code, of calling the ERR_PTR macro but not making use of the result, it seems that functionally platforms depend on the loop not existing here. The TI K3 families of platforms for example were broken by this commit. This reverts commit fe780310cfa8bf5a093894b5cd7fe85c6b02fd91.
