Subject: [PATCH] platform/x86: intel_pmc_core: Fix file permissions for ltr_show
Git-commit: cd89e92b7399a69512b8d855a2dd145c47399bf8
Patch-mainline: v5.1-rc1
References: bsc#1111666
File permissions for ltr_show attribute should be similar to other
debugfs attributes created by this driver. '0644' should be used only
when there is a write operation desired such as for ltr_ignore.
