[PATCH] hwmon: dell-smm-hwmon: remove unused variable warning

From: Arnd Bergmann
Date: Mon Sep 20 2021 - 08:14:39 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

When procfs is disabled, the code produces a warning
for an unused variable:

drivers/hwmon/dell-smm-hwmon.c: In function 'i8k_init_procfs':
drivers/hwmon/dell-smm-hwmon.c:624:31: error: unused variable 'data' [-Werror=unused-variable]
624 | struct dell_smm_data *data = dev_get_drvdata(dev);
| ^~~~

Remove that local variable and just pass dev_get_drvdata(dev)
directly.

Fixes: ba04d73c26ed ("hwmon: (dell-smm-hwmon) Move variables into a driver private data structure")
