Subject: [PATCH 3/3] kbuild: compile *.mod.c files with -fshort-wchar
Date: Fri, 28 Mar 2025 09:35:49 +0100 [thread overview]
Message-ID: <20250328083549.514506-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20250328083549.514506-1-a.fatoum@pengutronix.de>
We use wchar_t in USB and EFI code, both of which expect 2-byte wide
strings. Thus, like Linux, we set -fshort-wchar in KBUILD_CFLAGS.
This flag is not passed through to the build of *.mod.c files that are
generated in a module build, leading to a linker warning.
Add it to fix this.
