Subject: [PATCH] platform/x86: amd-pmc: Shuffle location of amd_pmc_get_smu_version()
Date: Mon, 18 Apr 2022 14:38:00 -0700 [thread overview]
Message-ID: <20220418213800.21257-1-nathan@kernel.org> (raw)
When CONFIG_DEBUG_FS is disabled, amd_pmc_get_smu_version() is unused:
drivers/platform/x86/amd-pmc.c:196:12: warning: unused function 'amd_pmc_get_smu_version' [-Wunused-function]
static int amd_pmc_get_smu_version(struct amd_pmc_dev *dev)
^
1 warning generated.
Eliminate the warning by moving amd_pmc_get_smu_version() to the
CONFIG_DEBUG_FS block where it is used.
Fixes: b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at probe time")
