Subject: [PATCH V4 1/8] staging: rtl8712: fix buggy size calculation
Date: Wed, 29 Jul 2015 06:49:58 -0700 [thread overview]
Message-ID: <1438177828-4752-1-git-send-email-stillcompiling@gmail.com> (raw)
In-Reply-To: <cover.1438057939.git.stillcompiling@gmail.com>
r8712_get_ndis_wlan_bssid_ex_sz has a "6 * sizeof(unsigned long)"
where the underlying struct has a 6 * unsigned char.
Simplify the calculation by just subtracting the variable part from
the size of the struct.
This also gets rid of a use of typedef NDIS_802_11_RATES_EX
