Subject: jtag_event_callback_t -> struct jtag_event_callback
X-Git-Tag: v0.4.0-rc1~785
X-Git-Url: https://review.openocd.org/gitweb?p=openocd.git;a=commitdiff_plain;h=363d72a48457e03d2ffdbf9154b8ba3fdb9197d0

jtag_event_callback_t -> struct jtag_event_callback

Remove useless typedef and redundant suffix from jtag_event_callback.
Add documentation for the structure.
