Subject: linux-6.12-rc1/drivers/iio/imu/bmi323/bmi323_core.c:133: Array
 contents defined but not used ?

Hello there,

I just tried to build linux-6.12-rc1 with clang. It said:

drivers/iio/imu/bmi323/bmi323_core.c:133:27: warning: variable 'bmi323_ext_reg_savestate' is not needed and will not be emitted [-Wunneeded-internal-declaration]

A grep for the identifier shows the following strange results::

inux-6.12-rc1 $ grep bmi323_ext_reg_savestate drivers/iio/imu/bmi323/bmi323_core.c
static const unsigned int bmi323_ext_reg_savestate[] = {
	unsigned int ext_reg_settings[ARRAY_SIZE(bmi323_ext_reg_savestate)];
	for (unsigned int i = 0; i < ARRAY_SIZE(bmi323_ext_reg_savestate); i++) {
	for (unsigned int i = 0; i < ARRAY_SIZE(bmi323_ext_reg_savestate); i++) {
linux-6.12-rc1 $ 

I see no mention of bmi323_ext_reg_savestate[ i]. Is there a possible
cut'n'paste error in one of the two for loops ?

Regards

David Binderman
