Subject: [patch] mwifiex: endian bug in mwifiex_drv_change_adhoc_chan()
Date: Thu, 1 Mar 2012 10:22:30 +0300 [thread overview]
Message-ID: <20120301072230.GC7152@elgon.mountain> (raw)
In mwifiex_drv_change_adhoc_chan() we pass channel to
mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits. This
works on little endian systems but not on big endian ones. I've changed
mwifiex_drv_change_adhoc_chan() to use a 16 bit variable. This matches
the other functions in the file.
I considered changing mwifiex_change_adhoc_chan() as well but it turns
out that the function isn't implemented so I just removed the
definition.
