From db005bdaa5ff4ea52095aa213507134dcaff42cc Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 21 Aug 2026 12:09:02 +0200 Subject: rtc: hym8563: Make sure clk_init_data is fully initialized The clk_init_data structure contains several mutually-exclusive members for different methods to specify the possible parents of a clock, prompting drivers to initialize only the members they need. However, not initializing all members may cause subtle issues, which are only exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is enabled. Make sure all members are fully initialized, to avoid such bugs, and to prevent future breakage when converting drivers to a different method for specifying the parents.
