Subject: airo: Fix integer overflow warning
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1f351e3840dcf25aaddec2d908c3ab06ae105ee6;p=openwrt%2Fstaging%2Fblogic.git

airo: Fix integer overflow warning

On BigEndian gcc complains:

drivers/net/wireless/airo.c: In function ‘sniffing_mode’:
drivers/net/wireless/airo.c:4809: warning: integer overflow in expression

Fix this by doing the bitwise AND on the host-endian value.
