[PATCH] power: supply: core: Fix a build failure due to psy_has_property() definition location

From: SeongJae Park
Date: Wed Sep 29 2021 - 09:02:28 EST


Commit 9ba533eb99bb ("power: supply: core: Add psy_has_property()") in -next
tree defines 'psy_has_property()' when 'CONFIG_THERMAL' is set. But, it is
also called from '__power_supply_register()', which is defined even if
'CONFIG_THERMAL' is unset. As a result, the build fails when 'CONFIG_THERMAL'
is undefined as below.

.../drivers/power/supply/power_supply_core.c: In function '__power_supply_register':
.../drivers/power/supply/power_supply_core.c:1137:6: error: implicit declaration of function 'psy_has_property' [-Werror=implicit-function-declaration]
1137 | if (psy_has_property(desc, POWER_SUPPLY_PROP_USB_TYPE) &&
| ^~~~~~~~~~~~~~~~
cc1: some warnings being treated as errors
.../scripts/Makefile.build:288: recipe for target 'drivers/power/supply/power_supply_core.o' failed
make[4]: *** [drivers/power/supply/power_supply_core.o] Error 1

This commit fixes the issue by moving the definition out of the '#ifdef' block.
