From a7b68ed15d1fd72c1e451d5eb6edebee2a624b90 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 7 Sep 2021 14:45:11 +0200 Subject: [PATCH] m68k: mvme: Remove overdue #warnings in RTC handling The warnings were introduced when converting the MVME147 and MVME16x RTC handling from gettod to hwclk. Replace the #warning by a comment, and return an error to inform the upper layer that writing to the RTC is not yet supported.
