Subject: [PATCH] memory: omap-gpmc: Fix build error without CONFIG_OF
Git-commit: 13d029ee51da365aa9c859db0c7395129252bde8
Patch-mainline: v5.10-rc1
References: git-fixes

If CONFIG_OF is n, gcc fails:

Drivers/memory/omap-gpmc.o: In function `gpmc_omap_onenand_set_timings':    omap-gpmc.c:(.text+0x2a88): undefined reference to `gpmc_read_settings_dt'

Add gpmc_read_settings_dt() helper function, which zero the gpmc_settings
so the caller doesn't proceed with random/invalid settings.

Fixes: a758f50f10cf ("mtd: onenand: omap2: Configure driver from DT")
