Subject: [PATCH 5.10 154/154] x86/Kconfig: Fix an unused variable error in dell-smm-hwmon
From: Randy Dunlap <rdunlap@...radead.org>
commit ef775a0e36c6a81c5b07cb228c02f967133fe768 upstream.
When CONFIG_PROC_FS is not set, there is a build warning (turned
into an error):
../drivers/hwmon/dell-smm-hwmon.c: In function 'i8k_init_procfs':
../drivers/hwmon/dell-smm-hwmon.c:624:24: error: unused variable 'data' [-Werror=unused-variable]
struct dell_smm_data *data = dev_get_drvdata(dev);
Make I8K depend on PROC_FS and HWMON (instead of selecting HWMON -- it
is strongly preferred to not select entire subsystems).
Build tested in all possible combinations of SENSORS_DELL_SMM, I8K, and
PROC_FS.
Fixes: 039ae58503f3 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")
