[sane-devel] Fix for backend/epson.c

[Aurelien Jarno]

Hi all,

H i have received a bug report via the Debian BTS.

In backend/epson.c, lines 823 and 905, there is the following code:

     const u_char * s = buf;

     for( k = 0; k < buf_size; k++) {
       DBG( 125, "buf[%u] %02x %c\n", k, s[k], isprint( s[k]) ? s[k] : '.');

The second argument passed to DBG, s[k], is a char, but the compiler is
tell to read an int. It seems to work in most case, but it mail fail on
some architectures.

The following patch should fix the problem.

Aurelien
