[PATCH] pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard

[Nathan Chancellor]

Clang warns when CONFIG_ACPI is unset:

 drivers/pinctrl/qcom/pinctrl-sdm845.c:1320:5: warning: 'CONFIG_ACPI' is
 not defined, evaluates to 0 [-Wundef]
 #if CONFIG_ACPI
     ^
 1 warning generated.

Use ifdef instead of if to resolve this.

Any of these others need the same s/#if/#ifdef/ ?

Patch applied with the ACKs.
I'm sure Bjorn doesn't mind.
