Subject[PATCH] staging: rtl8192e: use explicitly signed char
Date
With char becoming unsigned by default, and with `char` alone being
ambiguous and based on architecture, signed chars need to be marked
explicitly as such. In this case, passing `char *extra` is part of the
iw API, and that extra is mostly intended to be somewhat opaque. So just
cast to `s8 *` for the sign test. This fixes warnings like:

drivers/staging/rtl8192e/rtllib_softmac_wx.c:459 rtllib_wx_set_essid() warn: impossible condition '(extra[i] < 0) => (0-255 < 0)'
