commit c2bcc11a7f9d6f4a8dc37b7060e20b34bb120755 Author: Jorge Guzman <[email protected]> AuthorDate: Wed Jul 29 22:51:27 2026 -0300 arch/arm/src/stm32h7: fix LTDC format specifier for the CLUT index chromakey is a uint32_t, so printing it with %d warns. The line is only compiled when CONFIG_STM32_FB_CMAP is enabled, which is why it has gone unnoticed.
