objtool: Silence more KCOV warnings, part 2
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
Fixes: 6b023c784204 ("objtool: Silence more KCOV warnings")
