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")

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
