[PATCH 07/13] iwlwifi: clean up ht config a little

Reinette Chatre
2009-09-11T17:38:19Z

From: Johannes Berg <johannes@sipsolutions.net>

is_ht can be bool instead of u8, and there's
no need to use IWL_CHANNEL_WIDTH_* constants
in supported_chan_width when that could just
be named is_40mhz instead.
