The only reference to the mlxplat_mlxcpld_psu[] array got removed,
so there is now a warning from clang:
drivers/platform/x86/mlx-platform.c:322:30: error: variable 'mlxplat_mlxcpld_psu' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
static struct i2c_board_info mlxplat_mlxcpld_psu[] = {
Remove the array as well and adapt the ARRAY_SIZE() call
accordingly.
Fixes: 912b341585e3 ("platform/x86: mlx-platform: Remove PSU EEPROM from MSN274x platform configuration")

Thank you for your patch.
Note that there are 4 more cases where the foo1 and foo2 in:
.data = foo1 and .count = ARRAY_SIZE(foo2) are not the same.
There are 2 cases where .count is set to ARRAY_SIZE(mlxplat_mlxcpld_pwr)
instead of to ARRAY_SIZE(mlxplat_mlxcpld_default_pwr_items_data)
and there are 2 cases where .count is set to ARRAY_SIZE(mlxplat_mlxcpld_fan)
instead of to ARRAY_SIZE(mlxplat_mlxcpld_default_fan_items_data)
If one of the MLX people can provide a patch fixing this then that
would be great.
###
I've applied this patch to my review-hans branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
