Subject: [PATCH 2.6.18] [TRIVIAL] Simplify tosh_get_info() in drivers/char/toshiba.c

This patch against 2.6.18 is just a trivial simplification of tosh_get_info() 
in drivers/char/toshiba.c.
It was doing something like: b=a; b+=c; return b-a;
Replaced by: return c;
Also removed an unnecessary local variable.
