[drivers/power/supply/ab8500_chargalg.c:493]: (style) Variable 'ab8500_chargalg_ex_ac_enable_toggle' is assigned a value that is never used.

From inspection, this variable is never used. So remove it.

Hi Sebastian,

It looks like that this patch is not in linux-next 20220812
and I can still observe this build error with ARCH=arm, defconfig=allyesconfig.

Would you pick up this fix, please?

Thanks,
Miles
