Hi All,
Here is a patch to the jsm driver in the Linux (drivers/serial/jsm).
This patch takes care of (1) compiler warnings which displays the mixing
of declarations and code (2) dynamic allocation of major device number
instead of the static number 253 (3) the version update to reflect the
changes in the patch.
Please CC me your comments. Thanks.
