[PATCH 5.4 076/355] evm: mark evm_fixmode as __ro_after_init

[Greg Kroah-Hartman]

From: Austin Kim <austin.kim@xxxxxxx>

commit 32ba540f3c2a7ef61ed5a577ce25069a3d714fc9 upstream.

The evm_fixmode is only configurable by command-line option and it is never
modified outside initcalls, so declaring it with __ro_after_init is better.
