While building mxs_defconfig for arm with GCC 8, 9, 10 and 11, the following error was encountered:

/builds/linux/arch/arm/mach-mxs/mach-mxs.c:285:26: warning: duplicate 'const' declaration specifier [-Wduplicate-decl-specifier]
285 | static const struct gpio const tx28_gpios[] __initconst = {

/builds/linux/drivers/pwm/pwm-mxs.c: In function 'mxs_pwm_probe':
/builds/linux/drivers/pwm/pwm-mxs.c:164:24: error: implicit declaration of function 'dev_err_probe'; did you mean 'device_reprobe'? [-Werror=implicit-function-declaration]

| ^~~~~~~~~~~~~
| device_reprobe
cc1: some warnings being treated as errors
make[3]: *** [/builds/linux/scripts/Makefile.build:280: drivers/pwm/pwm-mxs.o] Error 1

This is also seen in other branches (from 4.4 to 5.4). To reproduce this build locally:

tuxmake \
--target-arch=arm \
--kconfig=mxs_defconfig \
--toolchain=gcc-11 \
--runtime=podman \
config default kernel xipkernel modules dtbs dtbs-legacy debugkernel headers
