From: Evan Green <evgreen@xxxxxxxxxxxx>
Subject: scripts/decode_stacktrace: Accept dash/underscore in modules
The manpage for modprobe mentions that dashes and underscores are
treated interchangeably in module names. The stack trace dumps seem
to print module names with underscores. Use bash to replace _ with
the pattern [-_] so that file names with dashes or underscores can be
found.
For example, this line:
[ 27.919759] hda_widget_sysfs_init+0x2b8/0x3a5 [snd_hda_core]
should find a module named snd-hda-core.ko.
