[PATCH v1 1/5] mfd: intel-lpss: Revert "Add missing check for platform_get_resource"

From: Andy Shevchenko
Date: Fri Nov 24 2023 - 15:03:17 EST


This reverts commit d918e0d5824495a75d00b879118b098fcab36fdb.

The commit in question does not fix anything and only introduces
a duplication in the code. The main intel_lpss_probe() performs
all necessary checks.

While at it and in order of avoiding similar patches to come, add
a comment.
