Subject: [PATCH 5.9 21/75] ftrace: Fix DYNAMIC_FTRACE_WITH_DIRECT_CALLS dependency

From: Naveen N. Rao <naveen.n.rao@...ux.vnet.ibm.com>

commit 49a962c075dfa41c78e34784772329bc8784d217 upstream.

DYNAMIC_FTRACE_WITH_DIRECT_CALLS should depend on
DYNAMIC_FTRACE_WITH_REGS since we need ftrace_regs_caller().
