commit 926fe783c8a64b33997fec405cf1af3e61aed441 upstream.
Recent changes to count number of matching symbols when creating a kprobe event failed to take into account kernel modules. As such, it breaks kprobes on kernel module symbols, by assuming there is no match.
Fix this my calling module_kallsyms_on_each_symbol() in addition to kallsyms_on_each_match_symbol() to perform a proper counting.

Fixed for 6.1. Please cherry-pick 73feb8d5fa3b755bb51077c0aabfb6aa556fd498 too.
Both now queued up now, thanks.
