From d18b2a0f1a78871104695ba9d3b03274bf8e07a1 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 16 Jun 2023 18:15:55 +0200 Subject: [PATCH] pinctrl: tegra: avoid duplicate field initializers The drv_reg field is initialized both in the DRV_PINGROUP_ENTRY_N/DRV_PINGROUP_ENTRY_Y macros and in DRV_PINGROUP_Y. Since each pingroup expands both macros, the are always duplicate and turning on -Woverride-init (which is disabled by default) causes a huge amount of warnings like: drivers/pinctrl/tegra/pinctrl-tegra234.c:1384:27: error: initialized field overwritten [-Werror=override-init] 1384 | #define DRV_PINGROUP_Y(r) ((r)) | ^ drivers/pinctrl/tegra/pinctrl-tegra234.c:1397:28: note: in expansion of macro 'DRV_PINGROUP_Y' 1397 | .drv_reg = DRV_PINGROUP_Y(r), \ | ^~~~~~~~~~~~~~ drivers/pinctrl/tegra/pinctrl-tegra234.c:1447:49: note: in expansion of macro 'DRV_PINGROUP_ENTRY_Y' 1447 | #define drive_soc_gpio08_pb0 DRV_PINGROUP_ENTRY_Y(0x500c, 12, 5, 20, 5, -1, -1, -1, -1, 0) | ^~~~~~~~~~~~~~~~~~~~ ... Remove the intialization that is never used here.
