Subject: printk/index: Fix -Wunused-function warning
X-Git-Tag: v5.15-rc1~136^2~3^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bc17bed5fd73ef1a9aed39f3b0ea26936dad60b8;p=thirdparty%2Fkernel%2Flinux.git

printk/index: Fix -Wunused-function warning

If CONFIG_MODULES is n, we got this:

kernel/printk/index.c:146:13: warning: ‘pi_remove_file’ defined but not used [-Wunused-function]

Move it inside #ifdef block to fix this warning.
