From: Josh Poimboeuf jpoimboe@kernel.org
commit 55c78035a1a8dfb05f1472018ce2a651701adb7d upstream.
Similar to GCOV, KCOV can leave behind dead code and undefined behavior. Warnings related to those should be ignored.
The previous commit:
6b023c784204 ("objtool: Silence more KCOV warnings")
... only did so for CONFIG_CGOV_KERNEL. Also do it for CONFIG_KCOV, but for real this time.
Fixes the following warning:
vmlinux.o: warning: objtool: synaptics_report_mt_data: unexpected end of section .text.synaptics_report_mt_data
