Subject: [PATCH] wireless: ipw2x00: Remove unnecessary parentheses

Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

drivers/net/wireless/intel/ipw2x00/ipw2200.c:5655:28: warning: equality
comparison with extraneous parentheses [-Wparentheses-equality]
if ((priv->ieee->iw_mode == IW_MODE_ADHOC)) {
~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
drivers/net/wireless/intel/ipw2x00/ipw2200.c:5655:28: note: remove
extraneous parentheses around the comparison to silence this warning
if ((priv->ieee->iw_mode == IW_MODE_ADHOC)) {
~ ^ ~
drivers/net/wireless/intel/ipw2x00/ipw2200.c:5655:28: note: use '=' to
turn this equality comparison into an assignment
if ((priv->ieee->iw_mode == IW_MODE_ADHOC)) {
^~
=
1 warning generated.
