Subject: linux-next: build failure after merge of the battery tree

Hi all,

After merging the battery tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/power/supply/bq27xxx_battery.c: In function 'bq27xxx_battery_update':
drivers/power/supply/bq27xxx_battery.c:1767:14: error: unused variable 'has_ci_flag' [-Werror=unused-variable]
 1767 |         bool has_ci_flag = di->opts & BQ27XXX_O_HAS_CI;
      |              ^~~~~~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  698502318f51 ("power: supply: bq27xxx: expose battery data when CI=1")

I have applied the following patch for today:
