From f45d32d2cd183c09b6c9aa8689a91d6f2760b557 Mon Sep 17 00:00:00 2001 From: Biju Das Date: Thu, 17 Aug 2023 17:10:38 +0100 Subject: rtc: isl1208: Fix incorrect logic in isl1208_set_xtoscb() The XTOSCB bit is not bit 0, but xtosb_val is either 0 or 1. If it is 1, test will never succeed. Fix this issue by using double negation. While at it, remove unnecessary blank line from probe().
