[PATCH -next] ACPI: PRM: make symbol 'prm_module_list' static

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The sparse tool complains as follows:

drivers/acpi/prmt.c:53:1: warning:
 symbol 'prm_module_list' was not declared. Should it be static?

This symbol is not used outside of prmt.c, so marks it static.

Fixes: cefc7ca46235 ("ACPI: PRM: implement OperationRegion handler for the PlatformRtMechanism subtype")
