Uninitialized variable in info_scr.c (display_levels()).

[textbrowser]

The variable sig_qual_max should be initialized as the following conditions may not be true.

	if (linkstat.data.bss_signal_qual) {
		/* BSS_SIGNAL_UNSPEC is scaled 0..100 */
		sig_qual     = linkstat.data.bss_signal_qual;
		sig_qual_max = 100;
	} else if (sig_level) {
		if (sig_level < -110)
			sig_qual = 0;
		else if (sig_level > -40)
			sig_qual = 70;
		else
			sig_qual = sig_level + 110;
		sig_qual_max = 70;
	}

Thank you. The logic avoids using sig_qual_max if sig_qual has not been set (-1), but I will initialize it none the less.

Sorry to bother you again. The variable should be initialized to a non-zero value so as to avoid an unlikely division by zero.

sig_qual_max > 0 iff sig_qual > -1. It is not supposed to be used when sig_qual == -1.

OK. :)
